First, arrange the numbers in ascending order: $15.3, 16.5, 17.3, 18.8, 18.8, 18.8, 21, 23.4, 25, 25$. The mean is the sum of all numbers divided by the count: $\frac{15.3 + 16.5 + 17.3 + 18.8 + 18.8 + 18.8 + 21 + 23.4 + 25 + 25}{10} = 199.9 / 10 = 19.99$. The median, the middle value of the ordered set, is 18.8 (or the average of the two middle numbers, which are both 18.8). The mode, the most frequently occurring number, is 18.8 since it appears three times, more than any other number.
