One of the disadvantages of Fisher's least difference (LSD)method is that the probability of committing a:
A)Type II error increases as the number of pairwise comparisons increases.
B)Type I error increases as the number of pairwise comparisons decreases.
C)Type II error increases as the number of pairwise comparisons decreases.
D)Type I error increases as the number of pairwise comparisons increases.

Question

Quizplus · Accepted Answer

Fisher's LSD method controls the family-wise error rate (FWER) at a specified level, which means that the probability of making at least one Type I error across all pairwise comparisons is controlled. However, as the number of pairwise comparisons increases, the probability of making at least one Type I error increases. Therefore, the correct answer is D.
