Textbook Problem

A repeated-measures study and an independent-measures study are used to compare two treatments and both use a total of 20 participants. What are the df values for the two t tests?

To determine

To find: The degrees of freedom for both independent measures test and repeated measures test.

Explanation

The degrees of freedom (df) for the independent t-statistic is df=n1+n22.

Hence, with ntotal=20, it implies :

df=202=</
