QUESTION:

For which of the following would it be most appropriate to use an ANOVA to analyze the data?

ANSWER:

In order to determine the effectiveness of different diet plans, 90 people are randomly assigned to one of three groups: (1) low calorie diet, (2) low-fat diet, or (3) low-carb diet. At the end of 60 days, the number of pounds lost was recorded for each of the participants.

Explanation

There is a categorical explanatory variable (type of diet), with more than two categories, and a quantitative response variable (number of pounds lost).
