The relative frequencies can be represented graphically by a relative frequency line or bar graph or by a relative frequency polygon. Indeed, these relative frequency graphs will look like the corresponding graphs of the absolute frequencies except that the labels on the vertical axis are now the old labels (that gave the frequencies) divided by the total number of data points.

Now, we can rearrange the table with a running-total as frequency. This frequency is called cumulative frequency.A cumulative frequency table consists of classes up to a certain upper value and cumulative frequencies, which takes the following form.

The graph below is an example of a Cumulative Relative Frequency Polygon: C. Cumulative Percent Polygons: Cumulative Percent Polygons are created in the same manner as the cumulative frequency polygon and the cumulative relative frequency polygon with the only difference being that you use cumulative percent values on the y-axis.

Ogives do look similar to frequency polygons, which we saw earlier. The most important difference between them is that an ogive is a plot of cumulative values, whereas a frequency polygon is a plot of the values themselves. So, to get from a frequency polygon to
