Answer 1

Range of the given data is 90

Step by Step Explanation :-

Given:

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

To Find :

Range of the given data

Solution:

To find the range of the given data, first we should arrange the given numbers in ascending order.

Ascending Order: 10, 20, 30, 40, 60, 70, 80, 100

Highest Value is 100 and Lowest Value is 10.

Range = Highest value - Lowest value

Range = 100 - 10

Range = 90

Hence, Range of the given data is 90
