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