Students study the characteristics of the F distribution and discuss why the distribution is not symmetric (skewed right) and only has positive values.
In Problem 1, students explore the characteristics of the F distribution. Then they will determine whether the graph changes when the degrees of freedom are interchanged.
Problem 2 explores the variances of two samples if F is near 1. They will also find critical values using the Fcdf command on the home screen and then confirm the answer using the ShadeF tool to find the area under the curve.
In Problem 3, students find the critical values for an F distribution. They first find the F value for a given area and construct confidence intervals. Students will check their critical values by using the ShadeF tool.
