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
