Trang 4During the last decade of the 21st century, internet shopping had grown in a surprising speed.With the fast development in internet and technology, people are no longer need to go out for their shopping since they can use e-retailing for almost everything they need Although e-shopping has its huge potential to even replace the traditional way of shopping, it has its ownproblem It is when people only use website for reference, and then they come directly to thephysical store to pick up their items
This research is conducted to find out the critical factors that can measure the customers’ intention to use e-retailing From several studies about this topic, especially the theory of reasoned action (TRA), there are four factors may affect to the customer’s intention They are trust, subjective norm, website quality and perceived risk in using credit card
In order to conduct the research, a sample size of 150 questionnaire about clothing products arecollected with respondents are office employees in Ho Chi Minh city Then, the data are
analyzed by reliability test, EFA and multiple regression analysis
Result of the thesis shows that the customers’ intention to use e-retailing is impacted only bytrust and subjective norm Therefore, it is suggested that owners of the business should try togain trust of their customers and encourage people to shop by groups
Since this research only focused in fashion products in Ho Chi Minh city, furthers studies in this field should be conducted for other types of products and in other provinces in Vietnam tofind out the general model for Vietnamese e-retailing

INTRODUCTION 1.1 Research background
E-retailing, also known as online shopping, internet shopping or e-shopping, can be
explained as an electronic commerce when buyers and sellers virtually meet others through a web browser Unlike traditional shops that require physical locations, physical security servicesand specific timeframes to operate, internet shops need none of those requirements Customers can access to the shop from anywhere and anytime they like as long as they have internet connection and an appropriate device like a computer, a tablet or a smartphone Since people are more and more busy with their job and internet has been widely and easily accessible, e-retailing has “redefined business and customer relationships, business processes, even
sometimes restructuring the whole industry by providing new distribution channel, new
delivery methods, new payment methods and new medium for communication” (Dogerlioglu and Cosgun, 2012) People had forecasted that in 2014 US e-retailing business can earn up to
$291 billion dollars in sale (Trends & Data - Internet Retailer)
With the tremendous opportunity to grow and a very promising market to exploit,
e-retailing has been attracting many scholars and experts to make researches in order to become successful in this new method of selling products As the results of that, many factors had been explored to contribute to a successful online business In 2009, Liao and Shi found that in Hong Kong market, where people tend to shop in groups, social influence should be a big factor that influence on the shopping behavior Even internet retailing does not require people
to go out for shopping, owners of the e-retailing business still need to think of ways like
spreading information as wide as possible, focusing on group buying, encouraging buying activities, etc
group-Another research about internet shopping in Malaysia showed that one of the most important factors that lead to the customers’ intention is their attitude towards e-retailing (Ting
& Lim, 2012) In that research, the authors also highlighted the easiness, usefulness and
1
Trang 10effortless when customers interact with the web pages can create the favorable shopping intention Besides the attitude towards e-retailing, Gefen, Karahanna and Straub (2003) added that customers’ trust played a significant role in increasing customers’ intention to shop online.They also proved that trust in e-vendor can be gained when people know that shop owners earn nothing more by cheating, a shop is safe to make transaction and the website is optimized
to be friendly and easy to use
As mentioned above, since e-retailing has been developed with a rocket speed, there are thousands of researches have been made only for gaining customers’ intention towards
internet shopping However, not many of them were made specifically for Vietnamese market.Therefore, it is an interesting topic to discover and study
1.2 Problem statement
In Vietnam, although traditional retailing is still playing a significant role, internet
shopping has been developed so rapidly and become more important According to Phan (2013), 36% of Vietnamese people are using internet and they generated a 700 million US dollars in revenue for e-retailing Although e-shopping only accounted for 0.3 to 0.5% of the total retailing revenue in Vietnam (according to Green Global, 2013), it can increase up to 2 times - 1.3 billion US dollars in 2015 (according to the Ministry of Industry and Trade)
However, internet shopping has its own problem It is because many of the internet users only go to the websites to find information, the price and comments about the products but they hesitate to make the paying transaction or products reservation (Ting & Lim, 2012) Vietnamese customers would rather go direct to the shop and buy the things they saw on web As the result of that, e-shopping as they know is nothing but an advertising or
marketing channel
Nguyen (cited by vnexpress.net, 2014), a lecturer in Electronic Commerce faculty,
University of Commerce stated that:
In Vietnam, most of Vietnamese businesses are small or medium businesses They are companies that can only afford small investments but want to try electronic commerce in the belief that they can be fast
Trang 11successful in this field However, I fear that doing business like that will lead to failure for most companies Investing in e-retailing requires much more money than people think Moreover, life
in Vietnam is not that industrialized that people have to go online for shopping.
Therefore, Vietnamese e-retailing market is very challenging to small and medium
businesses but it is also very promising with the prospect of fast developing and huge revenue
it can generate The problem is how an internet based retailing business can connect to the end clients and persuade them to make transactions through their sites It is why the research was conducted, to find and understand what significant factors affecting the intention of people to use e-retailing
1.3 Research objectives
As discussed in Section 1.1, e-retailing business is not only very promising in Vietnam butalso very challenging In order to be successful in this field, people firstly need to discover what factors can drive the shopping intention of clients Therefore, this research aims to:
- Identify critical factors affecting customers’ intention to use e-retailing
- Identify the level in which each factors affecting customers’ intention to use e retailing
1.4 Research questions
There are two questions to be answered to solve the problem identified in Section 1.2:
- What are critical factors affecting customers’ intention to use e-retailing?
- What is the level of impact of each factors affecting customers’ intention to use retailing?
e-1.5 Research scope
First of all, surveys questionnaire are collected only in Ho Chi Minh city – this is the most crowded city in the country and also known as the biggest economic center in Vietnam Second, only clothing products were researched It is because clothing products are easy to store and deliver (compare with grocery or electronic products) Besides, clothing products are fast to produce and people tend to change their clothes so many times during a year Especially,
3
Trang 12clothing products are manufactured by seasons, even when a cloth is quite new, people still change it to others when season changes Finally, the research focus in office employees
since they spend lots of their time sitting in front of a computer, have the opportunity to use internet almost daily and have good knowledge about computer or internet activities
1.6 Research significance
Because of the development of e-retailing, customers now have more choices to buy their needs They can choose either going to the shop to pick up the products when they have time orsitting in front of an internet devices and performing a transaction to get their products E-retailing therefore brings benefits not only to consumers but also to sellers People can shop whenever they like and sellers can sell almost 24/7
This research aims to discover the significant factors affecting customers’ intention to use e-retailing in Vietnamese context Results of the thesis may contribute to the academic knowledge in terms of Vietnam e-retailing market and Vietnamese consumers’ decision
factors It can help business to understand what affects to customers’ intention when they try their services Therefore, they can define a better strategy and customize their service to havebetter e-shopping experiences to attract to more customers For a general picture, the researchmay contribute, to some extent, to develop the Vietnamese e-retailing market in the future
1.7 Research structure
This research consists of five chapters First chapter is the introduction that presented the overview about the topic, the purpose of the research and the approached way to solve the
research’s problem Next chapter is the literature review where prior studies about internet
shopping had been reviewed in order to propose the conceptual model and hypotheses Chapter 3
is about the research methodology in which the research process is discussed Then, Chapter 4 about data analysis illustrates the testing of survey data In Chapter 4 also, results of the proposed model are presented Final chapter is about conclusion and recommendations where research findings and managerial implication are discussed In this chapter, the limitations of
Trang 13the research are mentioned in order to provide the directions for further researches about customers’ intention to use e-retailing the future.

Trang 14of buying online, the reality is that we do spend lots of time searching for products’
information and specifications on the internet According to ReachLocal (2012), 21% of the time people spending on the internet is for searching only and 61% of internet users research for their products online (Interconnected World: Shopping and Personal Finance, 2012)
Andam (2003) has defined e-retailing as a form of e-commerce - “a range of online
business activities for products and services” E-retailing can be understand as a B2C
e-commerce, a commerce between companies or shops and customers, it involves
customers’ purchasing both kinds of goods (physical and informational) and receiving
them over an electronic network (Andam, 2003)
Trang 15Back to the mid of 1990s, the founding of Amazon and eBay can be named the origin of retailing The early success of the two companies signaled the huge changes could happen in the way people run their business Since buyers know that they can save lots of time traveling
e-to see and buy a product, they can stay at home, use some clicks and have products delivered e-totheir home the next day or two That was just so simple and convenient Consumers using internet shopping not only save time but they are also allowed to save cost since they have chances of choosing the most competitive products among internet sellers Not long time after the Amazon and eBay succeeded, many internet based retailers were founded and then they completely redefine the retailing industry According to Deloitte, e-commerce accounted for a significant share of total retail revenue for the top 50 e-retailers in fiscal year 2012, accounting for nearly one-third of company sales on average
Not only brings huge benefits to consumers, but e-retailing also makes significant
improvement to the resellers Andam (2003) stated that e-retailing can reduce the market barriers since the cost of setting up and operating a website is much cheaper than building a traditional “brick and mortar” shop He also said that for a country with robust internet
population, delivering informational goods (electronic books, digitized contents or
software) becomes significantly potential
2.2 Customers’ intention to use e-retailing
Defined by Ajzen (1991, p.181), an intention is ‘‘indicators of how hard people are willing
to try, of how much of an effort they are planning to exert” In another study, intention was referred to” the individual’s assessment of the subjective probability that people will perform aparticular behavior in the future”(Söderlund & Öhman, 2003, p.54) In e-retailing context, Bai,Law and Wen (2008) stated that purchasing intention is a primary result of pre-purchase
satisfaction Chen, Hsu and Lin (2010) even confirmed that the online shopping intention is the significant predictor of actual buying behavior Applying to this research, customers’ intention to use e-retailing is defined as the expectation or intent of customers to perform the online purchasing in the future
7
Trang 16Theory of reasoned action (TRA) is one of the famous models that widely used to predict the behaviors of customers based on their behavioral intention Derived from numerous
researches and theories about customers’ attitude, TRA model was proposed by Ajzen and Fishbein (1975 & 1980) It suggests that the immediate antecedent of a behavior is the
intention to perform the behavior in question (Fishbein and Ajzen, 1975) It can be seen that the stronger the intention people want to try something, the higher the possibility that they may actually do it In the context of this research, customer’s intention can be defined as the intent
or expectation of a customer to purchase products via internet channels There are three key factors to form the construct, they are two independent factors that are used to define the
behavioral intention First factor is person’s attitude and the second is subjective norm
- Person’s attitude Generally, attitudes can be understood as the beliefs about the results of performing an behaviors and the evaluation of those expected outcomes
- Subjective norm In a simple form, subjective norm can be defined as the opinion of one person on how he/she thinks others should view them if they perform a behavior
The summary of TRA model can be expressed as the Figure 2.1:
Alternatively, in a simple form, TRA can be written as a formula:
W: empirically derived weights
(Dillard & Pfau, 2002 )
Trang 17Figure 2.1 The theory of reasoned action
(Vallerand et al., 1992)
Because of the possibility to predict the people intention towards a behavior, TRA had been used in a variety of contexts and industries For example, Vallerand, Deshaies, Cuerrier,Pelletier and Mongeau (1992) had used TRA to research about the moral behavior and they found that both attitude and subjective norm positively supported the model Particularly, attitude did prove to be more important to predict a behavior than subjective norm
Alternatively, another research made in Thailand by Chuchinprakarn (n.d.) also found that attitude and subjective norm did influence the customers’ intention to shop on-line
In this thesis, in addition to the TRA model, other models and researches are included tohelp explaining the customer’s intention In details, internet retailing quality (IRQ) and customers’ perceived risk in using credit card are added to form the research model
As defined in Section 2.1, e-retailing is a new way of purchasing products when consumers only need an electronic device and internet connectivity to perform a transaction Since internet
9
Trang 18shopping is also a service, the concept of quality applied in this context is similar to
conventional service quality As such, e-retailing quality should incorporate all of the functionalaspects of the service process as well as the technical ones of the service outcome (Gronroos et al., 2000; Collier and Bienstock, 2006) According to Parasuraman et al (2005, p.217), internet retailing can be defined as “the extent to which a web site facilitates efficient and effective
shopping, purchasing and delivery” In other to measure the e-retailing quality, there are number
of scales had been created, some of them are summarized in Table 2.1
As seen from the Table 2.1, one of the most important dimensions to measure e-retailing quality is the website quality Website quality is a significant factor in internet shopping since
“the customers’ perceptions of website quality positively impact their intentions to use a site and directly affect purchase intentions” (Chang, Kuo, Hsu & Cheng, 2014, p.256) In a simpleway, website quality is defined by its content and user interface A high quality website needs
to provide relevant and useful content along with its good and easy user interface It is so simple since almost all actions customers have to make to perform a purchase are placing on
a web browser Therefore, in this research, instead of using IRQ in general, website quality will be measured to examine the customers’ intention to use e-retailing
Perceived risk is defined as uncertainties of possible negative consequences of using a product or service (Chang, Kuo, Hsu & Cheng, 2014) In this research, perceived risk in using credit card refers to the uncertainties of people that they may lose money when purchasing products online The financial loss due to credit card fraud is a primary concerns among onlinecustomers (Dai, Forsythe & Kwon, 2014)

Trang 212.3 Factors impact to the customers’ intention to use e-retailing
2.3.1 Research model
Based on the TRA model and other researches that explained the customers’ intention toward a behavior, the research model is proposed in Figure 2.2 This model contains fourindependent factors, including trust, subjective norm, website quality and perceived risk
in using credit card, that affecting the intention of customers to purchase product online
In addition, three more demographic variables were used to test whether the characteristic
of customers have any significant difference on their intention
Trust
Gender
Age Income
Using Credit Card
Figure 2.2 Research model Hypothesis 1: Trust has a positive effect on the customer's intention to use e-retailing.
Hypothesis 2: Subjective norm has a positive effect on the customer's intention to use
Trang 22Hypothesis 5: Characteristics of customers have significant difference on their intention use
e-retailing
2.3.2 Trust
According to the TRA model (Ajzen & Fishbein, 1980; Fishbein & Ajzen, 1975), the best predictor of a future behavior could be the behavioral intention One of the influences on the intention is the person’s attitude toward performing the behavior Generally, attitudes can be understood as the beliefs about the results of performing a behavior and the evaluation of those expected outcomes It “represents the person's general feeling of favorableness or
unfavorableness for the behavior in question" (Ajzen & Fishbein, 1980) So the more positive people believe in the behavior, the more likely they intend to perform it
However, since personal attitude is a very wide range to study, the author had narrowed it down by using only one of its components So, trust was considered as one of the best choices Recently, trust had been widely discussed as a key factor for a successful online business In term of a business, trust is defined as “the consumers’ belief and expectation that e-sellers are reliable and will perform their obligations faithfully” (Chuchinprakarn, n.d.) Trust is an
important factor affecting consumers’ behavior and it may contribute to the success of
technologies adoption such as e-commerce (Chen & Barnes, 2007; Holsapple & Sasidharan, 2005; Goles et al., 2009; Yang et al., 2003) It can be seen that buyers are more likely to make transactions on the internet if they know that sellers are trustworthy and reliable Unlike
physical store that people can come and try the items, online shops have almost no thing to guarantee customers that their items are exactly what people can see in their websites Because
of that, customers’ trust even plays a more critical role to the intention of purchasing online then buying by traditional method According to a report from Yahoo Finance in 2012, the top three counterfeited products in America are all related to clothing items, i.e wearing apparels and accessories, watches and jewelries, handbags and wallets It is said that one of the source todeliver fake products is the online shop since people can not touch the real items but only read their info on the websites Although the availability and easiness of buying a product is
Trang 23changing since the booming of internet usage, there is an old-fashioned value that every
business needs to maintain – it’s customer’s trust
Since trust could significantly effects on e-retailing, first hypothesis is proposed as:
H1: Trust has a positive effect on the customer's intention to use e-retailing.
2.3.3 Subjective norm
In a simple form, subjective norm is the opinion of one person on how he/she thinks others should view them if they perform a behavior In a research, they define subjective norm as a social factor referring to the perceived social pressure to perform or not to perform the behavior(Ajzen and Madden, 1986) Normally, a social circle of a person includes his or her peers, which constitute siblings, friends and acquaintances (Pilgrim & Lawrence, 2001)
According to Liao and Shi (2009), the influence from a social group should not be ignoredsince the surrounding may highly affects to individuals to perform a behavior Especially in Vietnam where people are more collectivistic than individualistic, social norm may even has
a more important role impacted to the intention of people Clasen and Brown (1985) stated that an individual who belongs to a group may adapt his habits according to that group, he then complies with the dominant traits of that group to form his own trait, intentionally or unintentionally
Therefore, it is a reality since we know sometimes people are very positively affected by subjective norm They may not be favorable to a behavior or consequence but they do want to perform it because they believe in their referents It is the time when people feel motivated to perform a behavior According to Davis and Vekatesh (2000), working environment positivelyaffects to the individual behavioral intention Lee, Cheung, Sia and Lim (2006) also found thatthe positive informational social influence could enhance the relationships between customers’attitude about internet shopping and their intention to shop
In this research, the social norm that affects the customers’ intention to use e-retailing is referred to the customers’ co-workers and friends People working in the office meet their peersvery frequently, almost day-to-day basis so they are likely to be more up to date with new
14
Trang 24trends in fashion products As discussed earlier in this section, Vietnamese people are
collectivistic, like many other Asian countries, so they have a tendency to follow others An office employee may feel very isolated if he or she can’t catch up with the new trends in his/her office
At such, social influence is believed to have significant impact to the customers’
intention to shop online Therefore, the second hypothesis is proposed as:
H2: Subjective norm has a positive effect on the customer's intention to use e-retailing.
2.3.4 Website quality
Pinho et al (2011) was successful to discover the influence of website quality
characteristics on intention of users in applying online services They found that factors
including research facility, provides detailed information, privacy and security, interaction facilities and contacts, speed and facility of access, availability of relevant downloads,
reliable and up-to-date information are the most important qualifications of a website The research results presented that website quality increases intention of the users
In another research of Bai, Law & Wen (2008) about the direct effect of website quality
on customer satisfaction and purchase intention in China, they concluded that customer
satisfaction and purchase intention are directly influenced by website quality Jeong, Fiore, Niehm, and Lorenz (2009) found that rich website design elements can enhance the users’ interest and experiences, which in turn increased their intention to purchase
Wolfinbarger and Gilly (2003) stated that when customers interact with an online store they prefer to do their shopping through a technical interface and do not need the existence of any employees Therefore, the design of the website, which acts as the interface, would play animportant role in influencing customer satisfaction
Therefore, hypothesis three is proposed as:
H3: Website quality has a positive effect on the customer's intention use e-retailing.
Trang 252.3.5 Perceived risk in using credit card
Perceived risk in using credit card is the uncertainties of financial loss when using credit card for online purchasing Consumers are worried to give their personal information
particularly data on financial status and credit facilities to the internet because of the fact that there is no direct eye-contact and thus, consumers are concern about unauthorized use of theirprivate information (Grabner-Kraeuter & Faullant, 2008)
Chakravorti (2003) stated that people are hesitate to make their online purchasing by credit card since they are afraid that they cannot afford their payment when the card is on due date It is
a real risk because people may over consume their money without having control on their
balances It can lead to financial debt in the worst case when consumers have to pay additional feeand interest In a research conducted by Salam, Rao and Pegels (2003), they found that consumerswill highly stop making transactions over internet if for some reason, the potential loss of finance
is too high They stated that “the consumer’s perception of risk associated with the transaction willtend to predominate in his/her decision to engage in a transaction”
At the result of that, the hypothesis four is proposed as:
H4: Perceived risk in using credit card has a negative effect on the customer's use e-retailing 2.3.6 Demographic variables
In testing the customers’ intention use e-retailing, this research also included some
demographic variables The purpose is to know whether characteristics of consumers have any significant effect on their intention to perform the internet shopping Three variables are
chosen to investigate, they are gender, income and age
In 2002, Burke (as cited in Suki, 2011) stated that demographics (gender, age,
education) are key moderators in the online shopping environment Whitely (1997) also
confirmed that males are more positive and less anxious about technology innovations,
which are very likely to happen in the world of online retailing As growing older, people areless likely to access online information and using websites for shopping (Suki, 2011)
Therefore, the fifth hypothesis is proposed as:
16
Trang 26H5: Characteristics of customers have significant difference on their intention use e-retailing In
summary, this chapter is written to review researches conducted in the past to find the model thatcan predict the customers’ intention to use e-retailing By revising TRA model and other studies,
four factors were chosen to form the research model They are trust, subjective
norm, website quality and perceived risk in using credit card From the four factors, onlyperceived risk in using credit card has the negative impact on the customers’ intention
In addition, three demographic variables were added to the model to find out if gender, age or income affect to the customers when they choose to shop online

measurement scale and research hypotheses
3.2 Measurement scale of factors
First part of the questionnaire consists of three demographic questions including gender, age and income of the respondents Then, respondents were asked to give their opinion about the e-retailing in the next part consisting of 19 questions They would give their opinions about trust, subjective norm, website quality, perceived risk in using credit card and the intention to use e-retailing In this part, questions were measuring in interval five-point Likert scale – they are (1)– Totally disagree, (2) – Disagree, (3) – Neutral, (4) – Agree and (5) – Totally agree
Trust (TR): there are five statements to ask to measure the customers’ trust toward the
e-retailing shop, derived from Doney and Cannon (1997)
Subjective norm (SN): three questions are used to capture the information about this
variable, adopted from Liao and Shi (2009)
Website quality (Wb): measurement scales from Francis (2007) is used in addition with one
statement from the author, totally there are five items to measure this construct
Perceived risk in using credit card (PR): the perceptions of customers on using credit cards
is measured by three items, based on Liang, Lu and Tu (2006)
Intention to Use E-retailing (Int): four statements to ask to measure the customers’
intention to use e-retailing, based on Lim and Ting (2012).

Trang 303.3 Pilot test
Before conducting the main survey, a pilot test was made At this stage, five people
were chosen, from various companies and industries, to ask if they understood the survey clearly without any explanation from the author The purpose of this part is to refine the
questions when it was translated to Vietnamese Feedbacks of respondents was used to
enhance the readability and quality of the questions Next, the questionnaire was refined
after collecting feedbacks of the pilot test from respondents
paper, data were all collected in the period of mid July 2014 to August 2014
Since the number of questions in the survey are 19 (excluded the demographicquestions), the total of respondents should be at least 95 (5 times than the number ofquestions) to ensure that the data would be sufficient to run statistical analysis
In order to collect feedbacks, hard copy surveys are sent handedly to respondents to ensurethat they would answer all questions completely For the electronic versions, questionnaire was designed by using Google form Then, emails were sent to each respondents, all are office employees, there is a link to the survey in that email
There were 200 surveys sending out in both types From the feedbacks received, there were
150 found to be usable The others had to be ignored due to some errors such people did
not complete 100%, people answered all questions with identical values, etc However, 150
is considered a good number to be analyzed in term this research
3.5 Data analysis method
Collected data were coded before analyzing in SPSS software First, reliability test was done
by examining the Cronbach’s Alpha of the constructs in research model Next, EFA was
Trang 31conducted to verify the validity of items in the constructs Then, multiple regression analysiswas used to test the research hypotheses After that, ANOVA analysis was used to test the difference of demographic variables on the intention of consumers to use e-retailing Pre-requisites of those tests are included in the next chapter when each test is illustrated.
In summary, this chapter presented the process in which the research was conducted Thereare six steps that were performed from defining the research problem, literature review and hypotheses, design questionnaire, pilot test, data collection to data analysis and results The chapter also discussed the statistical methods used in testing measurement scale and research hypotheses, including reliability test, EFA and multiple regression model

Trang 32Characteristics of the dataset were examined by the three demographic questions in section
1 of the questionnaire From the data collected, the author would summarize the data as below:
- Gender: 58 of 150 respondents were male, accounted for 39% The rest were female, accounted for the 61% of respondents
- Age: of the 150 people, only 3 are in the age of 18 to 22 years old (2%), 59% of
respondents were in the age to 23 to 30 (88 people) 49 people (33%) were 30 to 40 years old.The rest 10 of people were above 40 years of age, accounted for 7%
- Income: in this category, most of people were asked to complete the survey had income lower than 15 million VND per month Of the three range below 15 million VND, the number were almost equally distributed 32% of all people received less than 5 million VND per month(48 people), 29% had 5 million to 8 million VND per month (43 people) and 41 people earned
8 million to 15 million per month (27%) The last 12% of total people could earn more than 15 million VND per month (18 people)
Summary of the sample characteristics is listed in the Table 4.1

4.2 Reliability test
In the reliability test, Cronbach’s alpha coefficients of each constructs were computed to estimate the reliability of the sample According to Leech and Barrett (2005), a Cronbach’s alpha number should be higher than 0.7 to be reliable In addition, a correlation of items
among a construct should be higher than 0.3 to indicate that those items are good components
of the factors Cited by Chong et al (2010), a coefficient ranges from 0.1 to 0.29 forms a weak
Trang 34correlation among components, from 0.3 to 0.49 forms the medium one and above 0.5 forms a strong correlation.
Results of the reliability tests, included Cronbach’s alpha coefficients and correlation matrixare illustrated in Table 4.2
