# SPSS Analysis For Average Recall Of Exact Phrases For Men And For Women

**Question**

Use the Christy.SAV data set for these problems.

1. Suppose the researcher wants to ask whether or not the average recall of exact phrases (VERBAL) for men and for women (GENDER) are different.

a. What test should the researcher run (be specific)?

b. Run the test. Report your test statistic, p-value, and effect size.

c. What should the researcher conclude?

2. Suppose the researcher is interested in whether or not there are differences in general recall (GIST) based on ethnicity (ETHNIC). For the OMNIBUS portion of this problem, assume alpha = .15.

a. What test should the researcher perform?

b. Run the test. What do you conclude? Look at the descriptive statistics. What problem do you see?

c. Run the analysis again. This time, fixing the problem that is present in Part B by deleting problematic case(s). Report your test-statistic, p-value, and effect size.

d. Do your results become more or less significant (i.e., closer to .05, or further from it)? Why do you think this is?

3. Suppose the researcher is interested in whether or not there are differences between the groups (GROUP) on gist recall.

a. What analysis would you run?

b. Run the test and report your test statistic, p-value, and effect size. What do you conclude?

c. Run the Bonferroni post-hoc test. Which conditions differ?

d. Run another post-hoc test on your results. Which conditions differ? How does this differ from the Bonferroni test? Why?

4. Imagine that the researcher had two measures that she gave each person and she wants to know if they differ. The first variable is VERBAL. The second variable is TOTAL. Is there a difference between the two?

a. What analysis would you run? Be specific

b. Run the analysis and report your test statistic, p-value, and effect size

c. What should the researcher conclude?

5. Suppose a researcher wants to know if verbal, gist, and total scores are all equal.

a. What analysis would you run? Be specific

b. Run the analysis and report your test statistic, p-value, and effect size

c. What should the researcher conclude? Be sure to tell me whether or not scores increase or decrease.

6. The research wants to know what impact group and gender together have on TOTAL scores.

a. What analysis would you run? Be specific

b. Run the analysis and report your test statistic(s), p-value(s), and effect size (s) – you need to do this for all the variables plus the combination (for all parts of this problem)

c. What should the researcher conclude at the omnibus level?

d. Run the appropriate follow-up test(s). What do you conclude?

JaneteHello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
