Is there a relationship among the variables measuring different aspects of customer satisfaction?
1. Run a Pearson correlation matrix using Delivery Reliability, Product Satisfaction, Technical Support, Sales Satisfaction, Overall Satisfaction in January, and Overall Satisfaction in June.
2. Create a scatterplot for the following pairs: (1) Delivery Reliability—Overall Satisfaction in June; (2) Product Satisfaction—Overall Satisfaction in June.
3. Report the descriptive statistics, assumptions tests, as well as tests of statistical significance identify of positive and negative relationships.
Question 2: Does delivery reliability impact overall satisfaction in June?
1. Run a simple regression using Delivery Reliability as the independent variable and Overall Satisfaction in June as the dependent variable.
2. Report the descriptive statistics, assumptions tests (scatter plots), as well as tests of statistical significance.
Question 3: Does delivery reliability and sales satisfaction impact overall satisfaction in June?
1. Run a stepwise multiple regression using Delivery Reliability and Sales Satisfaction as the independent variables and Overall Satisfaction in June as the dependent variable.
2. Report the descriptive statistics, assumptions tests (scatter plots), as well as tests of statistical significance.
