find the mean (average) of the following set of numbers: 4, 5, 2, 5
To find the mean (average) of a set of numbers, we add up all the numbers and then divide by the total count of numbers.
Adding up the numbers 4, 5, 2, 5, we get 4 + 5 + 2 + 5 = 16.
Since there are 4 numbers in the set, we divide the sum by 4 to find the mean: 16 / 4 = 4.
Therefore, the mean (average) of the set of numbers 4, 5, 2, 5 is 4.
