Question

14.) which of the following is not an advantage of factorial designs over one- way designs?

a.) they allow for greater generalizability.

b) they allow us to test an interaction.

c) they make it easier to deal with unequal sample sizes.

d.) they give us greater economy.

15.) when looking at multiple comparisons, the more tests that you run , the more likely that you have a ___.

a) type 1 error

b) type 2 error

c) mean squared error

d)random error

16 Fishers LSD test is most useful when

a) you have only one mean

b) you have two or three means

c) you have many means

d)you have a nonsignificant overall F.

17 An important assumption in the one way analysis of variance is that

a) observations are random.

b) observations are independent

c) subjects are related

d) there are equal numbers of observation in each group.

18 the analysis of variance compares

a the total variance with the variance within groups.

b the total variance with the variance between group means

c the variance between group means with the variance within groups

d the variance within groups with the variance among all data points.
