Answer 1

Given:

Data= 20,40,30,60,80,100,10,70

To find:

Range of the given data

Solution:

For finding the range of a given data, we need to arrange the numbers in the ascending order.

From lower to higher:

10,20,30,40,60,70,80,100

The range of a data= Highest value- Lowest value

In the given case:

Highest value= 100, Lowest value= 10

So, the range of the given data is 90.

The range of the data is 90.

The correct option is (C) 90.
