Who goes to movies?The bar graph displays data on the percent of people in several age groups who attended a movie in the past 12 months.

(a) Describe what the graph reveals about the relationship between age group and movie attendance.

(b) Would it be appropriate to make a pie chart of the data? Explain.

The given table is:

We can see that the highest bar in the bar graph corresponds to the category "18-24," then the age group most likely to attend a movie is 18 to 24 years old.

And the lowest bar in the bar graph corresponds to the category "75 and older," then the age group least likely to attend a movie is 75 and older.

We can see that each of the bars corresponding to these age categories has a height of at least 50, and the majority of the 18 to 54-year-olds appear to be going to the movies.

Because the bar corresponding to these age categories has a height of less than 50, it appears that the majority of the 55+-year-olds do not attend a movie.

In the bar graph, we can see that 74 percent of 18-24-year-olds, 65 percent of 25-34-year-olds, 60 percent of 35-44-year-olds, 52 percent of 45-54-year-olds, 47 percent of 55-64-year-olds, 30 percent of 65 75-year-olds, and 18 percent of 75+-year-olds go to the movies.

If we sum all of these percentages together, we get more than 100 percent, making a pie chart inappropriate.

Furthermore, because the different bars do not reflect a part of the same whole (as each age category is analyzed independently), a pie chart is not appropriate.
