A cumulative frequency table shows a running total of the frequencies. A cumulative frequency diagram reproduces this table as a graph. The table below shows the lengths of 40 babies at birth.
An alternative way of showing this data is to use a frequency polygon. The frequency is plotted against the midpoint of each group and the points are then joined by straight lines. Using the above ...
Cumulative frequency is a running total of the frequencies. The running total is calculated and recorded in an extra column on a frequency table. It can also be represented on a graph by plotting ...
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 ...
