Question

write the class size and class limit of the following:
104,114,124,134,144,154,164

Answer 1

Class size is 60 and class limit is 164

Answer 2

Hi friend,

size of each class = difference between the adjacent figure of the given data
= 114-104= 10
class size = 10
hence, Lower class limit = 104-1/2( class size)
= 104-1/2(10)
= 104-5
= 99
Upper Class limit = 104+1/2(class size)
= 104+1/2(10)
= 104+5
=109 .
Similarly we obtain other class limits as given at the top.
