Question

Quizplus · Accepted Answer

The appropriate test for ordinal data obtained from a three-group, matched-subjects design is the Friedman ANOVA by ranks. This test is used to compare three or more related groups to determine if there are any significant differences among them. It is a non-parametric test that uses ranks instead of actual values, making it appropriate for ordinal data. The T-test is used for comparing the means of two groups, the H-test is not a statistical test, and the U-test is a non-parametric test used for comparing two independent groups.
