Find the mean 9.8 7.2 6.3 5.8 9.4 5.1 6.2 7.2

7.125

Step-by-step explanation:

In mathematics, the 'mean' is the average of all the numbers.

We can find the average of a number group by adding together all of the numbers and dividing by how many numbers are included in the set.

9.8 + 7.2 + 6.3 + 5.8 + 9.4 + 5.1 + 6.2 + 7.2 = ?

9.8 + 7.2 + 6.3 + 5.8 + 9.4 + 5.1 + 6.2 + 7.2 = 57

Now how many numbers are in the given set: 9.8, 7.2, 6.3, 5.8, 9.4, 5.1, 6.2, 7.2

There are eight numbers in the given set. So now we divide our sum of all these numbers by 8.

57 ÷ 8 = 7.125

Thus, the mean (average) is 7.125.

Summary:

Mean = average

Average = sum of all numbers divided by how many numbers in the number set
