Question

What is the mean for the following set of data, to the nearest whole number? 5, 9, 15, 18, 22

Answer 1

14

Explanation:

To find the mean of a data set, add together all the values, then divide by the number of values.

Add all the values

Values: 5, 9, 15, 18, 22

Add: 5+9+15+18+22=69

Divide by the number of values. In this case, there are 5 values.

69/5

13.8

To the nearest whole number:

13.8

The tenth place is an 8, which is greater than 5, so we will round up.

13.8-->14

The mean is 14

Answer 2

13.8

Explanation:

First, add all the numbers up.

5+9+15+18+22=69

Now, divide this by the amount of numbers.

There are 5 numbers

69/5=13.8

Final answer

13.8
