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.
