• 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?
