How to find mean?

Find the sum of the values by adding them all up. Divide the sum by the number of values in the data set.

Given 10 results are 22, 43, 35, 32, 41, 28, 29, 30, 37, and 43.

Mean =  22+43+ 35+ 32+ 41+ 28+ 29+ 30+ 37+ 43 / 10

⇒ 340/10

⇒ 34

The answer is 34.

How do you find the mean in maths?
