1. Select Help > Sample Data Library and open Big Class.jmp.

2. Select Analyze > Fit Y by X.

3. Select height and click Y, Response.

4. Select sex and click X, Factor.

5. Click OK.

6. Click the red triangle next to Oneway Analysis of height By sex and select Unequal Variances.

Since the p-value from the 2-sided F Test is large, you cannot conclude that the variances are unequal.
