Question

How do you find the mean (average) of a data set?

Answer 1

To find the mean, you must add up all of the numbers in the data set and then divide them by the amount of numbers there are.

Explanation:

For example:

1, 2, 3, 4, 5

To find the mean, we first add up all of these numbers:

1 + 2 + 3 + 4 + 5 = 15

Next, since there are 5 total numbers here, we divide their sum by 5:

15/5 = 3

That is how we get the mean (or average) of the data set.
