Question

Calculate the range and coefficient of range of the following distribution: 120,100 , 130, 50,150​

Answer 1

Answer:

range =largest - smallest no.= 150- 50= 100

Answer 2

Answer:

The range of the given data is 100

The coefficient of range is 0.5

Step-by-step explanation:

Given data is 120, 100, 130, 50, 150

To calculate range:

We know that range is the difference between the highest value in the given data

=> Range = Highest value - Lowest value

                = 150 - 50

                = 100

Therefore, the range of the given data is 100

To calculate coefficient of range:

We know that coefficient of range = $\frac{L-S}{L+S}$

where L = Highest value in the given data

          S = Lowest value in the given data.

=> Coefficient of range = $\frac{150-50}{150+50}$

                                      =  $\frac{100}{200}$

                                      = $\frac{1}{2}$

                                      = 0.5

Therefore, the coefficient of range is 0.5
