Trang 9˃ To what extent is your research design really
focused on the problem statement you have?
˃ Will you collect and analyze relevant and accurate information?
˃ How can you be sure that your design answers your research questions?
˃ What aspects of the design can you create to
ensure validity?

Trang 11» To what extent does the literature review place your expected findings within a broader context?
» Will you be able to generalize from what you find?
» What limitations or qualifications will you have to make about your results?
» How can you extend your findings and suggest opportunities for further research so that you protect its validity?
» How does previous research help you interpret your results?
» Does previous research provide a rationale for your research design and suggestions about the applicability of your
findings?
