# The difference between the highest and the lowest observations of a data is called _________. Fill in the blanks to make the statement true.

**Solution:**

Given, the difference between the highest and the lowest observations of a data is called _________.

We have to fill in the blanks to make the statement true.

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

Example: consider 2, 5, 20, 17, 18

Arranging the __data__ in __ascending order__, we get

2, 5, 17, 18, 20

Highest observation = 20

Lowest observation = 2

__Range__ = highest observation - lowest observation

= 20 - 2

= 18

The range of the given data is 18.

Therefore, the difference between the highest and lowest observations is called range.
