Question

Draw an ogive to represent the following frequency distribution:
Class-interval
0-4
5-9
10-14
15-19
20-24
No. of students
2
6
10
5
3

Answer 1

Less Than Cumulative Frequency distribution table & Graph Of Less Than Ogive Is In The Attachment.

★★Here, the data is not in continuous form( exclusive) so we convert it into continuous form (inclusive).  For this subtract 0.5 from lower limit of each class interval and add 0.5 to upper limit of each class interval.

From the table : Plot these points (4.5, 2), (9.5, 8), (14.5, 18), (19.5, 23), (24.5,26)  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.
