The frequency distribution table for above distribution is :
| Marks | Cumulative frequency | Frequency |
|---|---|---|
| 0 - 10 | 100 | 13 (100 - 87) |
| 10 - 20 | 87 | 22 (87 - 65) |
| 20 - 30 | 65 | 10 (65 - 55) |
| 30 - 40 | 55 | 13 (55 - 42) |
| 40 - 50 | 42 | 6 (42 - 36) |
| 50 - 60 | 36 | 5 (36 - 31) |
| 60 - 70 | 31 | 10 (31 - 21) |
| 70 - 80 | 21 | 3 (21 - 18) |
| 80 - 90 | 18 | 11 (18 - 7) |
