Graphic representation of relative-frequency distributions can be obtained from the histogram or frequency polygon simply by changing the vertical scale from frequency to relative frequency, keeping exactly the same diagram. The resulting graphs are called relative-frequency histograms (or percentage histograms) and relative-frequency polygons (or percentage polygons), respectively. 40 FREQUENCY DISTRIBUTIONS [CHAP. 2 CUMULATIVE-FREQUENCY DISTRIBUTIONS AND OGIVES The total frequency of all values less than the upper class boundary of a given class interval is called the cumulative frequency up to and including that class interval.
