Question

In a frequency distribution , the mid value of a class is 20 and the width of class is 8 , then find the limit of class

Answer 1

Answer:

16-24

Step-by-step explanation:

Mid value (a) = 20

Width (h) = 8

Lower limit = a - h/2

= 20 - 8/2

= 20 - 4

= 16

Upper limit = a + h/2

= 20 + 8/2

= 20 + 4

= 24

Thus, the class limit = 16 - 24.

Also, a - h/2 and a + h/2 is the formula for finding out the lower and upper limit when class mark i.e mid value and class interval or width is given where a = mid value and h = width..
