Question

In a frequency distribution, the mid value of a class interval is 5 and the width of the class interval is 6. Find the lower limit of the class interval.

Answer 1

classmark = 5
class width =6
class interval = (5-6/2) to (5+6/2)
=(4/2)to(16/2)
=2 to 8
lower limit = 2

Answer 2

Answer:

2

class mark =5

Class width =6

Class interval =(5− 6/2) to (5+6/2)

(4/2) to (16/2)

=2 to 8

∴ Lower limit is 2
