F Distribution

Activity Overview

Students study the characteristics of the F distribution and discuss why the distribution is not symmetric (skewed right) and only has positive values. Students then use the Fcdf command to find probabilities and to confirm percentiles. They move on to find critical values and then compute a confidence interval.

Key Steps

Use pages 1.2 and 1.3 to introduce the F distribution. Have students then advance to pages 1.4 and 1.5 and compare this distribution to others they have seen.

Allow students to change the degrees of freedom for one or both samples.
