A repeated-measures ANOVA produced an F-ration of F = 4.00 with df = 1, 14. If the same data were analyzed with a repeated-measures t test, what would be the df value for the t statistic? 1 14 15 Cannot determine without more information

Solution

Given F with 1, 14 DF

DF1=1

NUMBER OF REPETITION =2=K

DF2=14

(K-1)*(N-1) =14    N=15

that means 15 subjects measured 2 times.

for paired t test , Df= 15-1 =14

Answer =14
