| Marks | No.of.students | Cumulative Frequency |
|---|---|---|
| Less than 10 | 5 | 5 |
| Less than 20 | 3 | 8 |
| Less than 30 | 4 | 12 |
| Less than 40 | 3 | 15 |
| Less than 50 | 3 | 18 |
| Less than 60 | 4 | 22 |
| Less than 70 | 7 | 29 |
| Less than 80 | 9 | 38 |
| Less than 90 | 7 | 45 |
| Less than 100 | 8 | 53 |
Let us create a table with the data required to draw the less than ogive by taking the Marks data and Cumulative frequency. The less than ogive is drawn with the x-axis as the less than values at each class interval plotted against the Cumulative frequency on the y-axis.
| Marks | Cumulative Frequency |
|---|---|
| Less than 10 | 5 |
| Less than 20 | 8 |
| Less than 30 | 12 |
| Less than 40 | 15 |
| Less than 50 | 18 |
| Less than 60 | 22 |
| Less than 70 | 29 |
| Less than 80 | 38 |
| Less than 90 | 45 |
