A repeated-measures ANOVA with four subjects who provide data in three conditions would have what critical value of F ($\alpha$ = .05)?
A) 4.76
B) 5.14
C) 3.98

Question

Quizplus · Accepted Answer

The critical value of F for a repeated-measures ANOVA depends on the degrees of freedom for the numerator (df1, related to the number of conditions minus one) and the denominator (df2, related to the interaction of subjects and conditions minus the number of conditions). With three conditions and four subjects, df1 = 3 - 1 = 2, and df2 = (4*3) - 3 = 9. Consulting a standard F-distribution table for α = .05 with these degrees of freedom, the closest critical value is typically around 5.14.
