An Ogive (cumulative frequency graph) is a graph that represents the cumulative frequencies of the classes in a frequency distribution. It shows the data below or above a particular value. The two types of Ogives are less than Ogive and greater than or more than Ogive.umulative relative frequency distribution is the ratio of the cumulative frequency to the size of the sample. The relative cumulative frequency or percentage cumulative frequency is the cumulative frequency divided by the total frequency.
