Question

What is the range of this data set?{5, 12, 15, 11, 15, 7, 15, 10, 13}8101215

Answer 1

We are asked to find the range of the following data

{5, 12, 15, 11, 15, 7, 15, 10, 13}

First, we need to sort the data in ascending order (least to greatest)

{5, 7, 10, 11, 12, 13, 15, 15, 15}

The range is given by

`Range=\max -\min`

The maximum value in the data set is 15

The minimum value in the data set is 5

So, the range is

`\begin{gathered} Range=\max -\min \\ Range=15-5 \\ Range=10 \end{gathered}`

Therefore, the range of the given data set is 10
