The numbers of laps are quantitative and do not contain any outliers. The most common and useful measure of center is the mean, which takes every data value into account. Thus, the best summary is the mean.

To summarize the swim team’s lap counts, the median is the best measure to use here. It’s less affected by extreme values, allowing us to see the central tendency of the more typical performances. Arranging the numbers gives us 80 laps as the median, providing a solid representation of the team’s ability without being skewed by the highest or lowest performers.
When considering the favorite animals from the children’s magazine readers, the mode is the right choice because it indicates which animal was selected the most frequently. This measure highlights popular preferences among the kids, capturing the collective spirit of their favorite choices rather than averaging out their diverse opinions.
