A
Survey of 50 Companies

In
January ‘08, fifty customers of a lumber manufacturer were surveyed regarding
their satisfaction with products and service. These customers buy from the
supplier and sell to retail chains like Home Depot and Lowes. Shortly after,
the manufacturing company was sold. In
June ‘08, the customers were telephoned and interviewed and were asked to rate
overall satisfaction again.

Variables in the working file

For each research question,
describe in your Microsoft Word document the application of the seven steps of
the hypothesis testing model.

Step 1: State the hypothesis (null and
alternate).

Step 2: State your alpha (unless requested
otherwise, this is always set to alpha = .05).

Step 3: Collect the data (use one of the
data sets).

Step 4: Calculate your statistic and
p-value. (This is where you run spss and examine your output files.)

Step 5: Accept or reject the null hypothesis.
(This is where you report the results of your analyses t (df) = t-value, p =
sig. level.)

Step 6: Assess the Risk of Type I and
Type II Error. (Did the data meet the assumptions of the statistic, effect
size, and sample size?)

Step 7: State your results in APA style
and format.

MODULE 5 Application Assignments

Question 1: Are there differences in perceptions of delivery
reliability between the companies who resell as a private label, manufacturer
brand, or a combination of both?

1. Run the one-way ANOVA.

2. Use type of company sales as the independent variable.

3. Use delivery reliability as the dependent variable.

4. Select descriptive statistics and tests of homogeneity.

5. Choose an appropriate post-hoc comparison to evaluate the
differences between groups.

Question 2: Did company size and structure of procurement
impact overall customer satisfaction in January?

1. Run a two-way between groups ANOVA.

2. Use size and structure of procurement as independent
variables.

3. Use overall satisfaction in January as the dependent
variable.

4. Report the descriptive statistics, assumptions tests,
effect sizes (partial eta) as well as tests of statistical significance.

Question 3: Has overall customer satisfaction changed since
the change in ownership? And, are smaller companies more satisfied than larger
companies?

1. Run a one-way between groups ANCOVA.

2. Use size as independent variables.

3. Use overall satisfaction in January as the covariate.

4. Use overall satisfaction in June as the dependent
variable.

5. Report the descriptive statistics, assumptions tests, effect
sizes (partial eta) as well as tests of statistical significance.

Write a brief conclusion statement summarizing your results.
What can you tell this manufacturing company about their customers? Has the
change in ownership improved customer satisfaction? What types of customers
seem to be most satisfied with this company?
