Which of the following describes the distinction between the LSD and the Bonferroni method of addressing post hoc comparisons? Question options:

1) The LSD method is more conservative than the Bonferroni method, and avoids more type I errors consequently making more type II errors.

2) The Bonferroni method is more conservative than the LSD method, and avoids more type II errors consequently making more type I errors.

3) The Bonferroni method is more conservative than the LSD method, and avoids more type I errors consequently making more type II errors.

4) The LSD method is more conservative than the Bonferroni method, and avoids more type II errors consequently making more type I errors.

Solution

Which of the following describes the distinction between the LSD and the Bonferroni method of addressing post hoc comparisons?

Here option 3) is correct because Bonferroni method results in a large reduction in the power of the tes that is type second error increases than only power is decreasing.

Therefore the correct answer is the Bonferroni method is more conservative than the LSD method, and avoids more type I errors consequently making more type II errors.
