Explanation / Answer
Using given frequencies we calculate cumulative frequency
28
Note:
Cumulative Frequency : Cumulative frequency is defined as a running total of frequencies. Cumulative frequency can also defined as the sum of all previous frequencies up to the current point.
In above frequency table there is a repetation of frequency that means 28 written as 2828 and 37 as 3737 so calculating cumulative frequency we not consider frequencies are 28, 37, 14, 2, 7, 2, 2
Age (years) of Best Actress When award was won Cumulative Frequency Less than 3028
Less than 40 = 28 + 37 = 65 Less than 50 = 65 + 14 = 79 Less than 60 = 79 + 2 = 81 Less than 70 = 81 + 7 = 88 Less than 80 = 88 + 2 = 90 Less than 90 = 90 + 2 = 92Related Questions
