• What is/are the independent variable(s)? What is/are the dependent variable(s)?

• What would be an appropriate null hypothesis? Alternate hypothesis?

• What are the degrees of freedom for 1) gender, 2) marital status, 3) interaction between gender and marital status, and 4) error or within variance?

• Calculate the mean square for 1) gender, 2) marital status, 3) interaction between gender and marital status, and 4) error or within variance.

• Calculate the F ratio for 1) gender, 2) marital status, and 3) interaction between gender and marital status.

• Identify the critical Fs at alpha = .05 for 1) gender, 2) marital status, and 3) interaction between gender and marital status.

• If alpha is set at .05, what conclusions can you make?
