1.

As variability due to chance (random error) decreases, the value of F will:

Select one:

b. stay the same

c. decrease

d. become 0

e. cannot tell from the given information

2.

When do you run a post-hoc test in ANOVA, and what is its function?

Select one:

a. When you fail to reject the null hypothesis and to determine significant between group differences

b. When you reject the null hypothesis and to determine significant between-group differences

c. When you fail to reject the null hypothesis and to set the value for the F test (or chi-square)

d. When you reject the null hypothesis and to set the value for the F test (or chi-square)

e. Always, so as to determine whether those groups have reliable differences

3.

Answer 1

1) a. increase (since it is the ratio of errror due to treatment and error due to chance)

2)
