Question

which box plot represents data that contains an outlier?

Explanation:

Step1: Recall the definition of an outlier in a box - plot

In a box - plot, an outlier is represented as a single point (dot) that is separated from the rest of the data (the whiskers and the box).

Step2: Analyze each box - plot

• In the first box - plot: The dots are close to the box and whiskers, no clear outlier.
• In the second box - plot: The dots are close to the box and whiskers, no clear outlier.
• In the third box - plot: There is a dot that is far away from the box and whiskers (the left - most dot is separated by a long distance from the box), which is an outlier.
• In the fourth box - plot: The dots are close to the box and whiskers, no clear outlier.

Answer:

The third box - plot.
