Given :

100,89,70, 44, 60,75,80,77,44,40,57,65,58,90,85,61,49,76,

93,52,87,43,51,73,82,69,71,41,91,47​

To Find : make 7 number of classes

frequency, relative frequency and class mark for each class

Solution:

Class Interval  CM         frequency f        relative frequency f/∑f

35   - 45           40               5                    5/30 = 1/6

45  - 55            50               4                     4/30 = 2/15

55 - 65            60                4                     4/30   = 2/15

65 -  75           70                 5                     5/30 = 1/6  

75 -  85           80                 5                     5/30 = 1/6  

85 -  95           90                 6                     6/30  = 1/5

95 - 105          100                 1                     1/30  

                             Total        30
