Independent Samples Ttest
The first step when opening the nQuery program
is to click File and then New.
A dialog box will appear that looks like this:
Since we intend to perform an independent samples ttest, we would
check off means, Two, and Test. Upon doing this, three options will
appear in the lower box. Choose twosample ttest. Since the sample
size in each group is different, also check the box labeled unequal
n's.
