What is a class width?
In a frequency distribution table, a class width can be defined as the difference between the upper (maximum) and lower (minimum) boundaries of any class in a data set. This ultimately implies that, all classes must all have the same width in a frequency distribution table.
How to calculate cumulative frequency?
In Mathematics and Statistics, the cumulative frequency of a data set can be calculated by adding each frequency from a frequency distribution table to the sum of the preceding frequency.
Frequency Cumulative frequency.
2 2
4 2 + 4 = 6
3 6 + 3 = 9
12 9 + 12 = 21
1 21 + 1 = 22
2 22 + 2 = 24
1 24 + 1 = 25
