PRDV420: Practice: t-test | Saylor University

In this exercise, you will use the t-test and Wilcoxon test to compare the Examination rates across the two groups. This exercise does not count toward your grade. It is just for practice!

Exercise:

Use the variable Agriculture in the built-in dataset swiss to separate the dataset into two groups: one with the Agriculture variable below its median and another with Agriculture above the median.
Use the t-test and Wilcoxon test to compare the Examination rates across the two groups.
Do the tests agree with each other?
