# A published report of a repeated-measures research study includes the following description of the statistical analysis. “The results show significant differences among the treatment conditions F(3, 21) = 6.10, P < 01.” a. How many treatment conditions were compared in the study? b. Mow many individuals participated in the study?

a.

To determine
The numbers of treatment conditions compared in the study.

Explanation

Given info:

In a repeated-measures study, results show significant differences among the treatment conditions, F(3,21)=6.10, p<0.01.

Calculation:

Let k represents the number of treatment conditions.

In this F-ratio with F(3,21)=6.10, the degrees of freedom corresponding to MSbetweenâ€‰treatments is 3

b.

To determine
The numbers of individuals participated in the study.
