Step 4: View StatMate's report

We'll choose the sample size chosen in approach B. In step 3 of StatMate, each value is a link. We click the link in the 80% power column and the N=25 row (52.68), and StatMate presents a complete report.

The screen shot above shows the first two of four sections of the report: a reiteration of your choices, and a detailed interpretation. The report then shows the entire table of tradeoffs (which you have already seen) and a discussion of when it makes sense to design studies with unequal sample sizes.

You may view the entire report for this example as a pdf file. You can send the entire report to Word with a click of a button (Windows only), or via copy and paste.
