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 a data point that is significantly different from the rest of the data. It is represented as a single point outside the whiskers of the box - plot.

Step2: Analyze each box - plot

• For the first box - plot: All the points are within a relatively close range and there is no distinct point outside the whiskers.
• For the second box - plot: There is a single point (the one with the red cross) that is separated from the main body of the data (the box and whiskers). This point is an outlier.
• For the third box - plot: All the points are within a reasonable range related to the box and whiskers.
• For the fourth box - plot: All the points are within the range defined by the box and whiskers.

Answer:

The second box - plot (the one with the red cross) represents data that contains an outlier.
