Less than ogive is a rising curve.

Graphical Representation of Cumulative Frequency Distribution.

*Cumulative Frequency Curve or an Ogive Curve.

An Ogive is a shape consisting of a concave arc flowing into a convexarcs. So forming
an S-shaped curve with vertical ends.

Graphical representation of cumulative frequency distribution is of two types

1.Less than type Ogive
2.More than type Ogive

*More Than Type Ogive

It is the graph drawn between lower limits and cumulative frequencies of a distribution.
a)Here we mark the points with lower limit as x-co-ordinate and corresponding
cumulative frequency as y-co-ordinate and join them by free hand smooth curve.
b)This type of graph is cumulated downward.

Example:1- For the following frequency distribution, draw a cumulative frequency
curve of more than type and hence, obtain the median value.
