A researcher conducts an independent-measures study examining the effectiveness of a group exercise program at an assisted living facility for elderly adults. One group of residents is selected to participate in the program, and a second group serves as a control. After 6 weeks, the researcher records a combined score measuring balance and strength for each individual. The data are as follows:

Control Exercise

* n* = 10 * n = 15*

* M* = 12 *M* = 15.5

* SS* = 120.5 *SS* = 190.0

Does the exercise program have a significant effect? Use an alpha level of .05, two tails.

Compute Cohen’s *d* to measure the size of the treatment effect.

A researcher conducts an independent-measures, two-factor study using a separate sample of n= 15 participants in each treatment condition. The results are evaluated using an ANOVA and the researcher reports an F-ratio with df = 1, 84 for factor A and an F-ratio with df = 2, 84 for factor B.

a) How many levels of factor A were used in the study?

b) How many levels of factor B were used in the study?

c) What are the df values for the F-ratio evaluating the interaction?

A researcher conducts an independent-measures, two- factor study using a separate sample of n = 5 participants in each treatment condition. The results are evaluated using an ANOVA and the researcher reports an F-ratio with df = 1, 24 for factor A, and an F-ratio with df = 2, 24 for factor B.

A)

How many levels of factor A were used in the study?

B)

How many levels of factor B were used in the study?

C)

What are the df values for the F-ratio evaluating the interaction?

A researcher conducts an independent-measures, two factor study with two levels of factor A and three levels of factor B, using a separate sample of n = 10 participants in each treatment condition

a. What is the dfwithin?

b. What is the df value for the F-ratio evaluating the main effect of Factor A?

c. What is are the df value for the F-ratio evaluating the main effect of factor B?

d. What is the df value for the F-ratio evaluating the interaction between A and B?
