The mean, median, and mode is 18.5, 19, 15.

We have

15, 24, 18, 15, 21, 20, 15, 22, 19, 16, 15, 22, 20, 15, and 21.

In ascending order:

15, 15, 15, 15, 15, 16, 18, 19, 20, 20, 21, 21 ,22, 22, 23

n=15(number of observations)

The median is $\frac{n+1}{2} \\= > \frac{16}{2} =8th term$

Median: 19.

Mean:

$\frac{sum}{n}\\ \frac{278}{15} \\=18.5$

Mode: 15.
