GRAPH OF LESS THAN OGIVE IS IN THE ATTACHMENT.
Graphical representation of Cumulative frequency distribution is of two types: less than type ogive and more than type ogive.
An ogive is a shape consisting of a concave arc flowing into a convex arcs.
Less than type ogive:
It is the graph drawn between upper limits and cumulative frequencies of a distribution. Here, we mark the points with upper limit and x- coordinate and corresponding cumulative frequency as y- coordinate and join them by freehand smooth curve. This type of graph is cumulated upward.
