# The difference between the highest and the lowest observations in a data is its

(a) frequency

(b) width

(c) range

(d) mode

**Solution:**

We have to determine the difference between the highest and the lowest observations in a __data__.

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

Example: consider the data 19, 2, 13, 9, 7, 5, 24

Arranging the given data in __ascending order__, we get

2, 5, 7, 9, 13, 19, 24

The highest observation is 24

The lowest observation is 2

__Range__ = highest observation - lowest observation

= 24 - 2

= 22

Therefore, the difference between the highest and the lowest observations in a data is range.
