Fisher's least significant difference (LSD)multiple comparison method is flawed because
A)it will increase β; the probability of committing a Type II error
B)it will increase α; the probability of committing a Type I error
C)it will increase both α and β,the probabilities of committing Type I and Type II errors,respectively.
D)None of these choices.

Question

Quizplus · Accepted Answer

Fisher's least significant difference (LSD) multiple comparison method increases the probability of committing a Type I error (rejecting a true null hypothesis), thereby increasing the overall significance level (α). However, it does not directly affect the probability of committing a Type II error (β).
