What is the mean of the following set of numbers? 25 15 13 28

1 answer

The mean can be calculated by adding up all the numbers in the set and then dividing by the total number of numbers.

Mean = (25 + 15 + 13 + 28) / 4
Mean = 81 / 4
Mean = 20.25

Therefore, the mean of the set of numbers 25, 15, 13, and 28 is 20.25.
