The range of the data 14, 6, 12, 17, 21, 10, 4, 3 is
(a) 21
(b) 17
(c) 18
(d) 11

Solution:

Given, the data is 14, 6, 12, 17, 21, 10, 4, 3

We have to find the range of the given data

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

Arranging the given data in ascending order, we get

3, 4, 6, 10, 12, 14, 17, 21

The highest observation is 21

The lowest observation is 3

Range = highest observation - lowest observation

= 21 - 3

= 18

Therefore, the range is 18.
