Question

Q.3.Find the range and coefficient of range of the following data: 50,90,120,40,180,200,80​

Answer 1

Answer:

The given numbers are:

50,90,120,40,180,200,80

⇒ Here, the largest value =x m =200

the smallest value =x 0 = 40

⇒ Range=x m −x 0

=200-40

=160

⇒ Coefficient of range=( xm-x 0 )/(x m +x 0)

=(200-40)/(200+40)

=160/240

=0.667
