Part 1: Testing Differences between Means: T-Tests

Using the survey dataset, you are going to address the following research questions:

1. Are there differences in scores on the ICU total between males and females?
2. Are there differences in the number of alcoholic beverages between Latinos and non-Latinos?
3. Are those who report having intentionally stolen something more or less sensation-seeking based on scores from the ICU total?

1. For each research question (a – c), compose a null and research hypothesis.
2. Conduct an independent sample t-test in SPSS to determine if the data fail to reject or reject the null hypothesis at the alpha = .05 level.
3. For each set of hypotheses report your findings by describing and discussing the output provided by SPSS. Also, explain why a t-test was used in each case . Remember to report the appropriate statistics along with the effect size (note. follow APA format when reporting any statistics in text; make sure to properly interpret the effect size [Cohen’s d ] with regard to the strength of the effect). Make sure to discuss the findings in terms of the research hypothesis. Only turn in your write up from #s 1 through 3. (Copy and past your SPSS output to word) make sure the proper statistics are reported in your write-up of findings.

Part 2: Testing Differences between Means: ANOVAs

Using the survey dataset, you are going to address the following research questions:

A. Is level of support for the death penalty dependent on political party affiliation?

B. Are there mean differences in sensation seeking (BSSS total) across education level?

C. Are there differences in CU traits (ICU total) across race?

1. For each research question (a – c), compose a null and research hypothesis.
2. Conduct a one-way ANOVA in SPSS to determine if the data fail to reject or reject the null hypothesis. If a significant difference does exist, determine between which "group" or "groups" the significant difference lies using either Bonferroni's test or Games-Howell test depending on whether the assumption of variance is met (this means you must conduct a Levene's test).
3. For each set of hypotheses (null and research) write a paragraph describing and discussing the findings from the SPSS output. Remember to report the appropriate statistics along with the effect size (note. follow APA format when reporting any statistics in text; make sure to properly interpret the effect size [Eta Squared] with regard to the strength of the effect). Make sure to discuss the findings in terms of the research hypothesis.
