Ogive (statistics)

Along the horizontal axis, the limits of the class intervals for an ogive are marked.

Based on the limit values, points above each are placed with heights equal to either the absolute or relative cumulative frequency.

The shape of an ogive is obtained by connecting each of the points to its neighbours with line segments.

To do this, we draw a line from the point of 50% on the axis of percentage until it intersects with the curve.

The frequency polygon and ogive are used to compare two statistical sets whose number could be different.
