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 involves multiple pairwise comparisons, which increases the probability of making a Type I error (rejecting a null hypothesis when it is actually true) due to the increased number of tests. Therefore, as the number of pairwise comparisons increases, the probability of making a Type I error also increases.
