The cumulative frequency is calculated by adding each frequency from a frequency distribution table to the sum of its predecessors. The last value will always be equal to the total for all observations, since all frequencies will already have been added to the previous total.

How to calculate cubic feet
- From feet: length (ft) × width (ft) × height (ft) = cubic feet.
- From inches: length (in) × width (in) × height (in) ÷ 1728 = cubic feet.
- From yards: length (yd) × width (yd) × height (yd) × 27 = cubic feet.
- From cm: length (cm) × width (cm) × height (cm) ÷ 28316.85 = cubic feet.
How do you calculate cumulative frequency for dummies?
To figure out the cumulative frequency of each class, you simply add its frequency to the frequency of the previous class. In this example, for the $3.75 to $3.99 class, you add its class frequency (4) to the frequency of the previous class ($3.50 to $3.74, which is 6), so 6+4 = 10.
