Question

What is the class size of class interval 125 - 100.​

Answer 1

Answer:

112.5

Step-by-step explanation:

class interval = ( lower limit + upperlimit )/ 2

                      = (125+100)

                      = 225/2

                      = 112.5

Answer 2

Class width = upper class limit - lower class limit

so , 125 - 100 = 25

and interval = ( upper class limit + lower class limit ) / 2

125 + 100/ 2

= 112.5
