Question

The monthly profits (in Rs) of 100 shops are distributed as follows:
Profits per shop:
0-50
50-100
100-150
150-200
200-250
250-300
No of shops:
12
18
27
20
17
6
Draw the frequency polygon for it

Answer 1

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

From the table : Plot these points (0, 100), (50,88), (100, 70), (150, 43), (200,23), (250,6)  by taking upper class limit over the x-axis and cumulative frequency over the y-axis.

MORE THAN TYPE OGIVE:

It is the graph drawn between lower limits and cumulative frequencies of a distribution. Here we mark the points with lower limit and x- coordinate and corresponding cumulative frequency and y- coordinate and join them by freehand smooth curve. This type of graph is cumulated downward.
