Question

Some integers are marked on a board. What is the range of these integers?

Answer 1

The difference between the highest and lowest observations in a given data is called its Range.

$20$ is the highest and $-17$ is the lowest observation are on the board.

So, Range $=$ Highest $-$ lowest

$$\begin{gathered} =20-(-17) \\ =20+17 \\ =37 \end{gathered}$$

Hence, the range of these integers is $37$.
