The TWO-Way Between-Subjects ANOVA

A hyopthetical study investigated the extent to which heterosexual men and women are willing to forgive an opposite-sex partner for transgressions in a relationship. men and women participants completed a questionnaire where they read five different situations where an opposite-sex partner trangressed in a relationship. After each situation, participants rated their willingness to forgive on a scale from 1 (not to forgive at all) to 9 (definitely forgive). hence, total ratings could range from 5( all 1s recorded) to 45( all 9s recorded). Given the following data, test whether forgiveness varies by sex and/or relationship status at a .05 level of significance.

Sex	Short term relationship	long term relationship
men	18	8
men	24	22
men	12	20
men	9	11
men	12	5
men	29	21
men	13	25
men	9	30
men	32	28
men	36	28
women	28	18
women	34	32
women	22	27
women	19	21
women	14	14
women	27	32
women	28	25
women	28	24
women	31	25
women	20	25

With regard to the SPSS exercise, answer the following questions:

Based on the output shown in SPSS, complete the following F table (label each factor in the space provided in the first column):

Sources of Variation	SS	df	MS	F Statistic	Sig.
A
B
Error
Total

Based on the value of the test statistics, what is the decision for each factor in the two-way between-subjects ANOVA? (circle one)

Factor A: Retain the null hypothesis Reject the null hypothesis

Factor B: Retain the null hypothesis Reject the null hypothesis

A B interaction: Retain the null hypothesis Reject the null hypothesis

Based on the F table you just completed, state the following values:

Total sample size

Sample size per cell

Number of levels for Factor A (p)

Number of levels for Factor B (q)

Significance for each test:

Factor A

Factor B

A B interaction

If you find a significant interaction, output a plot and interpret the nature of the interaction.

State the conclusion for this test in APA format. Make sure you summarize the test statistic, each significant main effect, and significant interaction. Provide an interpretation for the statistics you report.
