1. Example-1

Calculate More than type Cumulative frequency table from the following grouped data
Class Frequency
10 - 20 15
20 - 30 25
30 - 40 20
40 - 50 12
50 - 60 8
60 - 70 5
70 - 80 3

Solution:

Class	Frequency
10 - 20	15
20 - 30	25
30 - 40	20
40 - 50	12
50 - 60	8
60 - 70	5
70 - 80	3

More than cumulative frequency can be obtained by adding to the other frequencies in the reverse order.

Class	Frequency	More than type	Cumulative Frequency
10 - 20	15	More than 10	88 (= 73 + 15)
20 - 30	25	More than 20	73 (= 48 + 25)
30 - 40	20	More than 30	48 (= 28 + 20)
40 - 50	12	More than 40	28 (= 16 + 12)
50 - 60	8	More than 50	16 (= 8 + 8)
60 - 70	5	More than 60	8 (= 3 + 5)
70 - 80	3	More than 70	3
