Question

Jason polled a large sample of individuals to find the entrance exam scores from 0 to 100 of out-of-state students. Which of the following would be an appropriate choice to display the results?

a. pie chart.
b. bar graph.
c. histogram.
d. dot plot.

Answer 1

c. histogram.

Explanation:

In this case, the most appropiate way to show the results is to group the results in classes (for example from score 0 to 20, 21 to 40, 41 to 60, until 100) and show the relative frequency for each of the classes.

An histogram allows us to present this information graphically in the ways described before.

A pie chart is appropiate to show proportions.

A bar graph is similar but for discrete or non-numerical categories.

A dot plot is adequate por discrete classes and small samples.
