The following table shows the number of runs scored by a certain batsman in different overs:
|
Over |
50-55 |
55-60 |
60-65 |
65-70 |
70-75 |
75-80 |
|
No. of runs |
2 |
8 |
12 |
24 |
38 |
16 |
Change the distribution to a "more than" type distribution, and draw its OGIVE on the graph.
We can obtain cumulative frequency distribution of more than type as following -
|
Over (lower class limits) |
Cumulative frequency |
|
More than or equal to 50 |
100 |
|
More than or equal to 55 |
100 - 2 = 98 |
|
More than or equal to 60 |
98 - 8 = 90 |
|
More than or equal to 65 |
90 - 12 = 78 |
|
More than or equal to 70 |
78 - 24 = 54 |
|
More than or equal to 75 |
54 - 38 = 16 |
Now taking lower class limits on x-axis and their respective cumulative frequencies on y-axis we can obtain its ogive as follows.
- 1
- 2
- 3
- 4
- 5
- 6
- 7
- 8
- 9
- 10
