Suppose a researcher sets up a design in which there are five different treatments and a total of 32 measurements in the study.For alpha = .01, the critical table F value is ____.
A)3.75
B)3.78
C)4.07
D)4.11
E)4.91

Question

Quizplus · Accepted Answer

The critical F value is determined by the degrees of freedom for the numerator (k-1, where k is the number of treatments) and the denominator (N-k, where N is the total number of measurements). Here, k=5 and N=32, so the degrees of freedom are 4 and 27, respectively. At alpha = 0.01, the critical F value is 4.11.
