Question

Find the mean of the following set of data. Round your answer to two decimal places. 13, 11, 4, 5, 6, 9, 10, 12, 15, 16

Answer 1

10.10

Explanation:

Mean is another term for the average!

It is calculated by adding up all of the terms, and dividing that number by the amount of numbers there are!

1) Add all of the terms:

101

2) Divide 101 by 10, because there are 10 numbers!

10.1

3) Round to two decimal places:

10.10 (add a zero!)

Answer 2

10.10

Explanation:

The mean of the data set is 10.10. To find the mean we have to calculate the sum of all the numbers and divide it by the amount of numbers there are. There are 10 numbers in this data set.

Calculate the sum of all the numbers :

13 + 11 + 4 + 5 + 6 + 9 + 10 + 12 + 15 + 16 = 101

Divide it by the amount of numbers there are :

101 ÷ 10 = 10.1

Round the answer to two decimal places :

10.1 - > 10.10 (Just add a zero since there aren't any recurring numbers)
