Answer 1

Question :-

• What is the range of the following data – 25, 18, 20, 22, 16, 6, 15, 12, 30, 32, 10, 19, 8, 20

Answer

Given : -

• The data 25, 18, 20, 22, 16, 6, 15, 12, 30, 32, 10, 19, 8, 20

To Find :

• Range of the given data

Method :-

The formula, used to calculate the range is:

R = H - L

where

• R = range
• H = highest value
• L = lowest value

The range is the easiest measure of variability to calculate.

To find the range, follow these steps:

• Order all values in your data set from low to high.
• Subtract the lowest value from the highest value.

Solution :-

The data is 25, 18, 20, 22, 16, 6, 15, 12, 30, 32, 10, 19, 8, 20

■ Arrange the above data in ascending order

6, 8, 10, 12, 15, 16, 18, 19, 20, 20, 22, 25, 30, 32

⇛ Highest value, H = 32

⇛ Lowest value, L = 6

So, Range = Highest vaue - Lowest value

So, Range = 32 - 6 = 26.
