Make a box-and-whisker plot of the data.
20, 23, 28, 14, 13, 24, 18, 11
To create a box-and-whisker plot of the data, we need to first find the five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum.
The data in ascending order:
11, 13, 14, 18, 20, 23, 24, 28
Minimum: 11
Q1: 14
Median: 19
Q3: 23
Maximum: 28
Now we can create the box-and-whisker plot:
Minimum: 11
Q1: 14
Median: 19
Q3: 23
Maximum: 28

This box-and-whisker plot represents the data visually, showing the distribution of the data and any outliers that may be present.
