# 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.
