Question

two consecutive class marks of a distribution are 52 &57 find the class limit​

Answer 1

Class size = Difference between consecutive class marks = 57-52 =5

Lower class limit = 52 - (5/2) = 52-2.5 = 49.5 [ Half of class size is subtracted]

Upper class limit = 52 + (5/2) = 52+2.5 = 54.5 [Half of class size is added]
