Question

the classmarks of a distribution are 47,52,57,62,67,72,77,82,87,92,92,102. Determine class size, class limits, true class limits​

Answer 1

the class marks of distribution are 47,52,57,62,67,72,77,82 determine the class size,class

Class size = Difference between class marks of two consecutive classes.= 52 - 47 = 5

Lower-class limit = class marks - 1/2 of class size= 47+2.5 = 49.5

Upper class limit = class marks + 1/2 of class size = 52+2.5 = 54.5

Since, the class-limits form a continuous frequency distribution; the true class limits and the class-limits are the

same
