Answer 1

The best measure of center to summarize the reading times is the median because it is less influenced by extreme values.

Step-by-step explanation:

The best measure of center to summarize the reading times would be the median because it is less influenced by the one very low value. Unlike the mean, which can be greatly affected by extreme values, the median is the value that divides the data set into two equal parts. This makes it a more reliable measure of center when there are outliers or extreme values present.
