Answer:
The mean is the average of a set of data.
Example:
To find the mean, add up all of the numbers in the set and divide by the number of values that you added.
35 + 36 + 37 + 38 + 40 + 40 + 41 + 42 + 43 + 55 + 55 + 55 + 56 + 57 + 58 + 59 = 747
Then, divide by the number of values, which is 16.
747/16=46.68
