PRACTICE 6
Question 1: Is there a relationship among the variables measuring different aspects of customer satisfaction?
- Run a Pearson correlation matrix using delivery reliability, product satisfaction, technical support, sales satisfaction, overall satisfaction in January and overall satisfaction in June.
- Create a scatter plot for the following pairs: (1) delivery reliability—overall satisfaction in June; (2) product satisfaction—overall satisfaction in June; and delivery reliability—product satisfaction.
- 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?
- Run a simple regression using delivery reliability as the independent variable and overall satisfaction in June as the dependent variable.
- Report the descriptive statistics, assumptions tests (scatter plots), as well as tests of statistical significance.
Question 3: Does delivery reliability and product satisfaction impact overall satisfaction in June?
- Run a multiple regression using delivery reliability as the independent variable and overall satisfaction in June as the dependent variable.
- Report the descriptive statistics, assumptions tests (scatter plots), as well as tests of statistical significance.
PRACTICE 7
Question 1: Before the change of ownership, the company was encouraging its customers to reduce private labeling as a way to reduce cost of goods sold. Explore the distribution of customers by purchase type. Does the distribution of customers (private label, brand label, or both) differ from what one would expect by chance? Does if differ they expect more brand labeling?
Question 2: Run a chi square goodness of fit using purchase type as the variable with "all categories equal" for the expected value.
- Run a chi square goodness of fit using purchase type as the variable with "all categories unequal" with 12, 26, and 12 as the expected values.
2. Report the observed and expected values and the tests of statistical significance.
Question 3: Is there a relationship between the company size and type of procurement?
Run chi-square independence test (crosstabs) using company size and type of procurement. U se the chi square and the phi coefficient to evaluate the relationship and statistical significance. Report the observed and expected values and the tests of statistical significance.
