This portion of the Final Exam draws upon the knowledge and skills you acquired throughout this course by asking you to perform an SPSS analysis. Read the three case studies below and choose the appropriate statistical procedure. Using the Final Exam Data Set, run the appropriate correlation or regressions procedure, analyze the data, and report the results in a properly formatted APA Results section.

Please be sure to include the following elements in your Results:

1. The assumption tests and their results (include graphs if you used them)

2. An adequate report of the descriptive statistics

3. The null hypothesis

4. The rationale for the chosen statistical procedure and results of the statistical procedure, including effect size and power

5. The decision regarding the null hypothesis

For the purpose of the Final Exam, do not transform or change any variables if assumptions are not met. Conduct and report the most appropriate parametric procedure; simply note violations and identify the nonparametric alternative that could be conducted.

You may consider the following parametric statistical procedures to respond to the questions:

• One-sample t Test

• Dependent t Test

• Independent t Test

• One-Way ANOVA

• Two-Way ANOVA

• Repeated Measures ANOVA

• Bivariate Correlation (Pearson r and Spearman rho)

• Partial Correlation

• Bivariate Linear Regression

NOTE: While you were allowed to work with your peers for the other SPSS Assignments, you must work individually for this Final Exam.

Case Study 1

An educational statistics professor is examining his grade book to determine the relationship and differences among a variety of assignment scores. He is examining these scores to determine if his course is effective. Every semester, the professor gives his students a pretest and a posttest to determine if they improved in their understanding of the course concepts. Thus, the first question he examines is as follows : Is there a difference in the number of points students earned on their educational statistics pretests and posttests?
