Definition of ogive diagram?

An ogive is a type of graph that is used to represent the cumulative frequencies for the classes in a frequency distribution. This type of graph can also be known as a cumulative frequency graph. The cumulative frequency is the sum of the frequencies accumulated up to the upper boundary of a class in the distribution.
