INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

a. Use the Titanic data set to investigate whether a passenger’s country of residence

affected the cost of their ticket. First, run your usual significance test without checking

assumptions. Briefly report your overall findings, including post-hoc comparisons and

what they found.

b. Then, examine the data for normality. If deciding this assumption has been violated,

explain how you know this and then run the appropriate non-parametric significance

test. Post-hoc analysis is not required here.

c. Formally summarize your findings (statistical and research), indicating which nonparametric test you used to obtain your results. Refer to your Evans text for examples of

non-parametric reporting.
