SHORTCUT KEYS

 Shortcut keys offer an easy way to navigate through records, fields, and select a single or range of values

CTRL + down arrow To get to the bottom row of your data set

CTRL +up arrow To get the top row of your data set

CTRL + right arrow To get to the last column of your data set

CTRL + left arrow To get to the first column of your data set

CTRL + Home To get to the first cell (top left) in your data set

CTRL + End To get to the last cell (bottom right) in your data set

Any of the Above + Shift To select an entire range

Summary of Shortcut Keys for Large Data Sets

SHORTCUT KEYS tasks

1 Quickly identify how many transactions are in the file;

2 What is the sales value of the last transaction in the

record set?

3 What is the sales value of the first transaction in the

record set?

4 Select all the dates of the transaction in the transaction

sales column

5 Select all the transactions and all the columns for each

transaction

 It can be used to total values that meet specified criteria in a given range.

 = SUMIF (range, criteria, [sum_range])

AVERAGEIF

 It can be used to average the values that meet specified criteria in a given range

 = AVERAGEIF (range, criteria,

[average_range])

 It can be used to count how many values meet specified criteria in a given range

 = COUNTIF (range, criteria)

Examples of Using SumIf, AverageIf, and CountIf Functions

 If a formula cannot properly evaluate a result, Excel will generate

an error value

 (#N/A, #VALUE!, #NAME?, #DIV/0! , or #NULL!.)

 Often, the decision maker needs to ignore these errors or

replace them with another value

 The IFERROR function

 It tests a cell or calculation to determine whether an error has been

generated It will show TRUE for any type of error and FALSE if no error

is found

 Syntax

 =IFERROR (Cell to be tested), where “Cell to be tested” can be a cell

reference or a formula.

Illustration of IFERROR Function

 The Transpose Function

 It copies data from a range, and places in it in a new

range, turning it so that the data originally in columns is now in rows, and the data originally in rows is in columns

 The transpose range must be the same size as the

original

 The function needs to be entered as an array formula

 Syntax

 =TRANSPOSE(Range)

STEPS to transpose rows into

columns and columns into rows

 Step 1: Select the range where the transposed table will be located

 Step 2: Enter ‘=Transpose (A2:D10)’ function in the upper left corner

of the selected, transposed table

 Step 3: Simultaneously, hit CTRL+SHIFT+ENTER keys and the

values will be accordingly stored in the transposed table

 It multiplies corresponding cells from two or more arrays and calculates the total of these products

 =SUMPRODUCT (array1, array2, array3 )

 The IF Function

 It can be used to returns one value if a certain condition

is TRUE and another value if the same condition is

FALSE

 =IF(logical_test, value_if_true, value_if_false)

 Three Components:

 Applying IF Statements to Calculate Sales Commissions

 Cutoff Points for the Commission Plan

PIVOT TABLE

 Pivot tables are a powerful data summary tool.

data into averages, sums, maximum values, minimum values, and so

on

dynamic pivot chart, filtering, sorting, and can be used to drill-down data.
