a histogram
a pie chart
a box - and - whisker plot
a stem - and - leaf plot
annual salary ($)
13,000 15,000
19,000 23,000
23,000 255,000
32,000 16,000
17,000 22,000
21,000 18,000

Explanation:

A box - and - whisker plot is useful for showing the distribution of data, including outliers. Here, the value \(255000\) is an outlier. A histogram is for showing the frequency distribution in intervals. A pie chart is for showing parts of a whole. A stem - and - leaf plot is more about showing the individual data points in an ordered way. Since we have an outlier, a box - and - whisker plot can effectively display the spread and the outlier.

Answer:

a box - and - whisker plot
