Create an Excel spreadsheet, and enter the following information:B3:Group

B4:1 Males

B5:2 Females

C3:n

D3:Mean

E3:STDEV

C4:52

D4:55

E4:7

C5:57

D5:64

E5:13

Now, widen column B so that it is twice as wide as column A, and center the six numbers and their labels in your table (see Fig. 5.8)

B8:Null hypothesis:

B10:Research hypothesis:

Let’s “break this formula down into pieces” to reduce the chance of making a mistake.B13:STDEV1 squared/n1 (note that you square the standard deviation of Group 1, and then divide the result by the sample size of Group 1)
