MODULE 6 Application Assignments
Question 1: Is there a relationship among the variables measuring different aspects of parent satisfaction?
1. Run a Pearson correlation matrix using Safety, Education, Social, Physical, Overall Satisfaction in January and Overall Satisfaction in June.
2. Create a scatterplot for the following pairs: (1) Safety—Overall Satisfaction in June; and (2) Education—Overall Satisfaction in June.
3. Report the descriptive statistics, assumptions tests, as well as tests of statistical significance. Identify strong and weak correlations.
Question 2: Does Safety Impact Overall Satisfaction in June?
1. Run a simple regression using Safety as the independent variable and Overall Satisfaction in June as the dependent variable.
2. Report the descriptive statistics, assumptions tests (scatterplots), as well as tests of statistical significance.
Question 3: Does Safety and Education Impact Overall Satisfaction in June?
1. Run a stepwise multiple regression using Safety and Education as the independent variables and Overall Satisfaction in June as the dependent variable.
2. Report the descriptive statistics, assumptions tests (scatterplots), as well as tests of statistical significance.
Write a brief conclusion statement summarizing your results. What can you tell this district about the relationship among satisfaction variables? Are there any areas they need to improve? Does adding a second variable to the regression equation increase prediction of parent satisfaction in June?
