Dr. X is curious about how music effects levels of happiness (yes, this again). She split her participants into four groups. The control group sat in a room for a half hour, the
experiential groups listened to either country, classical, or pop music for half an hour. After the half hour was up, she had the participants fill out a measure of happiness. Below are the results
of her study. The procedure and equations for this can be found on page 398-400 in your text book. The critical F value chart for ANOVA can be found on 394-395. Keep in mind the example in the book
has 3 conditions and this study has 4.
