A researcher in conducting a study to determine customers’ satisfaction with the service and
coverage they are receiving from telecommunication providers. A sample of 25 persons was chosen and each individual used one carrier for three weeks then switched to the others. The participants then rated the carriers on a scale of 1 – 20. The results are given below:
1. Use the data above to conduct a One-Way Repeated Measures ANOVA. What would you conclude from your hypothesis test? Clearly outline all steps. [6 marks].
2. How does this test differ from a One-Way ANOVA test? [2 marks].
3. Interpret and report on the relevant information presented in the following tables:
(i) Mauchly's test [2 marks]
(ii) Test for normality [2 marks]
(iii) Pairwise comparison [2 marks]
4. The JASP output of all the statistical analyses performed as well as the file that was
produced should be provided. [2 marks]
