Data set: Music
The students in the music and performance study in Exercise 5 also recorded an adjusted WPM score (i. e., the words per minute adjusted by the student’s accuracy).
a. Calculate an appropriate ANOVA for this study using adjusted WPM as the response. State your conclusions, taking into account random sampling and random allocation. Provide appropriate plots.
b. Assume these introductory statistics students asked you whether they should present WPM or adjusted WPM. What would you suggest? Explain why.
c. These students also considered using Accuracy as a response variable. Explain why they should be cautious about testing several different response variables and then choosing to present the one result with the smallest p-values.
