Given Four Populations with Equal Means and Equal Variances,an F

question 37

Multiple Choice

Given four populations with equal means and equal variances,an F distribution for situations with samples of 10 scores each could be created by

• A)applying the t test formula to each pair of samples,squaring the results to obtain F ratios,then repeating this process a large number of times.
• B)applying the analysis of variance formula to a set of four samples (one from each of the four populations)of 10 scores each,determining the degrees of freedom,and repeating this process a large number of times.
• C)taking 10 samples from each of the four populations,figuring the F ratio,and repeating this process a large number of times.
• D)taking samples of 10 scores from each of the four populations,figuring an F ratio for each set of samples,and repeating this process a large number of times.
