Ogive (statistics)

In statistics, an ogive, also known as a cumulative frequency polygon, can refer to one of two things:

any hand-drawn graphic of a cumulative distribution function^[1]
any empirical cumulative distribution function.

The points plotted as part of an ogive are the upper class limit and the corresponding cumulative absolute frequency^[2] or cumulative relative frequency. The ogive for the normal distribution (on one side of the mean) resembles (one side of) an Arabesque or ogival arch, which is likely the origin of its name.
