In this test we analyze repeated-measures (RM) data. For example, when 10 students are graded by three teachers the grades could look like:

H₀ for this test is that students get the same mean marks from all three teachers.

To run the test execute the command:

The results of the test are displayed in the table:

Since the F statistic is less than the critical value we can't reject H₀. To get the P-value for this test you can execute:

The result, 0.123532 is clearly larger than our default significance 0.05.
