Question

coefficient of range of the data,120,100,130,50,150 is​

Answer 1

Answer:

Step-by-step explanation:

The given numbers are 59,46,30,23,27,40,52,35,29.

⇒  Here, the largest value =xₐ=150 and the smallest value =x₀=50

⇒Range=xₐ-x₀

           =150-50

           =100

Coefficient of range = xₐ-x₀/xₐ+x₀

                                = 150-50/150+50

                                =  100/200

                                =  1/2            

                                = 0.5

Answer 2

Answer:

Coefficient of the range = 2/3 or 0.66

Step-by-step explanation:

Given data 120, 100, 130, 50, 250

rewrite the data in ascending order 50, 100, 120, 130, 250

⇒ formula for the coefficient of the rage is given by

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

 here L = largest value = 250 ,

          S = smallest value = 50

 ⇒ Coefficient of range = $\frac{250-50}{250+50}$ = $\frac{200}{300}$ = 2/3 = 0.66
