A two-factor study compares 2 levels of factor A and 3 levels of factor B with a sample of n = 10 participants in each treatment condition.For this study,the F-ratio for factor A has df = 2,54.

Question

Quizplus · Accepted Answer

The degrees of freedom for factor A in a two-factor study are based on the number of levels of factor A minus one. Since there are 2 levels of factor A, df for factor A would be 1, not 2. The second number in the df for the F-ratio typically represents the error or within-groups degrees of freedom, which would not be 54 in this context based on the information provided.
