Question

If the critical difference for the Tukey test equals 3 for α equal to .05, then a difference between means of 10 and 8 for two groups is ,. A)nonsignificant; p > .05 B)nonsignificant; p < .05 C)statistically significant; p > .05 D)statistically significant; p < .05

Quizplus · Accepted Answer

The critical difference is 3, which means that any difference between means that is less than 3 is not statistically significant at the α level of .05. The difference between means of 10 and 8 is 2, which is smaller than the critical difference of 3. Therefore, the difference is nonsignificant and p > .05.
