Movie Ratings Narrative
A movie critic wanted to determine whether or not moviegoers of different age groups evaluated a movie differently. With this objective, he commissioned a survey that asked people their ratings of the most recently watched movies. The rating categories were 1 = terrible, 2 = fair, 3 = good, and 4 = excellent. Each respondent was also asked to categorize his or her age as either 1 = teenager, 2 = young adult (20-34), 3 = middle age (35-50), and 4 = senior (over 50).
The results are shown below.
