Question

Draw a ‘less than’ ogive of the following data.
Marks: Less Than 20 Less Than 30 Less Than40 Less Than 50 Less than 60 Less Than 70 Less than 80 Less Than 90 Less Than 100 .
No. of students : 0 4 16 30 46 66 82 92 100.

Answer 1

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.
