Which of the following sets of data should not be displayed with a pie chart? Assume that only the given categories will be included.

a. the percentage of people who support a new speed limit law and the percentage of people who oppose the new speed limit law
b. the percentage of people who speak only one language and the percentage of people who speak multiple languages
c. the percentage of workers with college degrees and the percentage of workers without college degrees
d. the percentage of people who have a full-time job and the percentage of people who have a part-time job

The arc length of each segment is proportional to the magnitude of data (in percentage) it denotes, typically resulting in a figure alike to a slice of pie.

A pie chart is a used to display data that has stark dissimilarities within it.

A single pie chart can have any number of sections representing the various factors.

In a pie chart, on adding the percentages of all the factors the total value should come up as 100%.

Consider the data mentioned in option (d).

"the percentage of people who have a full-time job and the percentage of people who have a part-time job"

This data cannot be represented on a pie chart.

This is because there is one category or factor missing in this case, i.e. percentage of people who have no job.

Thus, the correct option is (d).
