find the frequency for each class interval.
locate the endpoint for each class interval.
calculate the cumulative frequency by adding the numbers in the Frequency column.
record all results in the table. To make cumulative frequency graph
To calculate the cumulative frequencies, add the frequencies together. A cumulative frequency diagram is drawn by plotting the upper class boundary with the cumulative frequency. The upper class boundaries for this table are 35, 40, 45, 50 and 55.
