1-61.

Find the mean and median for the lengths of the jumping frogs’ bodies shown below (the length are in centimeters). Homework Help ✎

20.3, 12.5, 7.6, 13.9, 9.2, 21.7, 7.6, 17.5, 15.6, 14.1

The mean is the average of all the lengths.

Add all the lengths of the jumping frogs together and divide that sum by the number of lengths.

The median is the middle number when the lengths are arranged numerically.

Since there are 2 middle numbers, average, or find the mean of, the two middle numbers.
