Cumulative Frequency
In statistics, the total frequency of a given value up to and including a certain point in a set of data. It is calculated by adding together the frequencies to give a running total and used to draw the cumulative frequency curve, the ogive.
To plot a cumulative frequency diagram, the cumulative frequency is always plotted along the vertical axis and data are always plotted at the top range of the interval: for example, frequency for weekly salary ranges £100–150 and £151–200 would be plotted at 150 and 200.
