Question

A student survey was conducted in a major university, where data were collected from a random sample of 750 undergraduate students. One variable that was recorded for each student was the student's answer to the question: What is your favorite type of movie? Action/Comedy/Drama/Family/Horror/Musical/Science Fiction. These data would be best displayed using which of the following?

A. histogram
B. IQR
C. boxplot
D. stemplot
E. pie chart

Answer 1

E. pie chart

Explanation:

The number of students who like each kind of movie is a natural value, like 20, 30, 40, ..., so it is a discrete value.

Histograms are for continuous data, divided in intervals.

IQR and boxplot are related to quartiles, which is not important for this question.

Stemplots also uses continuos data.

So the best choice here is finding the percentage of each movie. Percentages are displayed by pie charts.

So the correct answer is:
