Question

What is the mean of 10,12,15,11

Answer 1

Answer:

12

Step-by-step explanation:

To find the mean of a set of numbers, add all the numbers together. Then, divide the sum by how many numbers you had to begin with.

Add the numbers together:

10 + 12 + 15 + 11

= 48            This is the sum of the data

Count how many numbers you had:

10, 12, 15 and 11 are FOUR numbers (amount of data).

Divide the sum of the data by the amount of data.

48 ÷ 4 = 12         This is the mean

The mean of 10, 12, 15, 11 is 12.
