box plots
identifying a data set with an outlier
which box plot represents data that contains an outlier?

Explanation:

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

An outlier in a box - plot is a data point that is represented as a single point (dot) outside the whiskers of the box - plot. The whiskers of a box - plot typically extend to the minimum and maximum non - outlier values.

Step2: Analyze each box - plot

• In the first box - plot, there is a dot (data point) above the upper whisker. This dot is an outlier as it is separated from the main body (the box and the whiskers) of the box - plot.
• In the second box - plot, all the data points (dots) are within the range of the whiskers (or part of the box).
• In the third box - plot, all the data points (dots) are within the range of the whiskers (or part of the box).

Answer:

The first box - plot represents data that contains an outlier.
