Question

Quizplus · Accepted Answer

Fisher's LSD test is most useful when comparing two or three means. It is not as effective when dealing with many means and should only be used if the overall F test is statistically significant. Therefore, options A and C can be ruled out. Additionally, the fact that the overall F test is nonsignificant does not necessarily mean that the means are not significantly different from each other, so option D can also be ruled out.
