Read the case studies below and choose the appropriate correlation or regression procedure. Then, using the Correlation and Regression Data Set, run the appropriate correlation or regression procedure, analyze the data, and report the results in a properly formatted APA Results section. Be sure to include the following elements in the Results section: 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 results of the statistical procedure 5. The decision regarding the null hypothesis For the purpose of this assignment, do not transform or change any variables if assumptions are not met. Conduct and report the most appropriate parametric procedure; simply note violations. Submit this assignment in a Word document by the end of Module/Week 6.
Case Study 1 A fifth grade science teacher wants to know if there is a relationship between final exam scores and overall course points after adjusting for a quiz score. (Hint: In order to be successful, be sure to include a scatterplot to evaluate the various assumptions).
Case Study 2 The assistant principal wants to know if students' cumulative GPAs on an 8 point scale can predict students' final exam grades in their fifth grade science class. He wants to predict the final exam score of a student who has a GPA of 8.0. (In order to be successful, be sure to include a prediction equation, an APA-style regression table, and an APA-style scatterplot).
