$\begin{array}{c} Class & Frequency \\ 12 - 17 & 3 \\ 18 - 23 & 6 \\ 24 - 29 & 4 \\ 30 - 35 & 2 \end{array}$

Step 1

The cumulative frequency of a data class is the number of data elements in that class and all the previous classes.

$\begin{array}{c} Class & Frequency (f) & Cumulative - Frequency \\ 12 - 17 & 3 & 3 \\ 18 - 23 & 6 & 3 + 6 \\ 24 - 29 & 4 & 3 + 6 + 4 \\ 30 - 35 & 2 & 3 + 6 + 4 + 2 \end{array}$

Step 2

Simplify the cumulative frequency column.

$\begin{array}{c} Class & Frequency (f) & Cumulative - Frequency \\ 12 - 17 & 3 & 3 \\ 18 - 23 & 6 & 9 \\ 24 - 29 & 4 & 13 \\ 30 - 35 & 2 & 15 \end{array}$
