Finding the mean, step by step

The mean shares a total out equally: add every number, then divide by how many there are.

The question

Mean of 39, 41, 46, 18, 46

3941461846
3941461846
39 + 41 + 46 + 18 + 46 =190
3941461846
39 + 41 + 46 + 18 + 46 =190
190 ÷ 5 =38
  1. The mean is what every number WOULD be if the total were shared out evenly. So first find the total.
  2. 39 + 41 + 46 + 18 + 46 = 190.
  3. Now share it between all 5 of them: 190 ÷ 5 = 38.

How it works.

  1. 01

    The mean is what every number WOULD be if the total were shared out evenly. So first find the total.

  2. 02

    39 + 41 + 46 + 18 + 46 = 190.

  3. 03

    Now share it between all 5 of them: 190 ÷ 5 = 38.
