B)3 × 2; statistically significant
C)2 × 2; nonsignificant

Question

Suppose an experimenter manipulated type of music and the loudness of the music as independent variables. The results of an analysis of variance for the interaction were reported as F(2, 24) = 2.24, p > .05. Given this
A)2 × 2; statistically significant
B)3 × 2; statistically significant
C)2 × 2; nonsignificant
D)either a 2 × 3 or a 3 × 2; nonsignificant

Quizplus · Accepted Answer

The F statistic is associated with a p-value greater than .05, indicating the results are not statistically significant. The degrees of freedom (2, 24) suggest a factorial design with two levels of one independent variable and three levels of another, making it either a 2 × 3 or a 3 × 2 design.
