Less Than Cumulative Frequency distribution table & Graph Of Less Than Ogive Is In The Attachment.
From the table : Plot these points (640,16), (680, 61), (720,217), (760,501), (800,673), (840,732), (880,750) by taking upper class limit over the x-axis and cumulative frequency over the y-axis.
★★ 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.
