Calculate Less than type Cumulative frequency table from the following grouped data
| Class | Frequency |
| 0 - 2 | 5 |
| 2 - 4 | 16 |
| 4 - 6 | 13 |
| 6 - 8 | 7 |
| 8 - 10 | 5 |
| 10 - 12 | 4 |
Solution:
| Class | Frequency |
| 0 - 2 | 5 |
| 2 - 4 | 16 |
| 4 - 6 | 13 |
| 6 - 8 | 7 |
| 8 - 10 | 5 |
| 10 - 12 | 4 |
Less than cumulative frequency can be obtained by adding to the other frequencies.
| Class | Frequency | Less than type | Cumulative Frequency |
| 0 - 2 | 5 | Less than 2 | 5 |
| 2 - 4 | 16 | Less than 4 | 21 (= 5 + 16) |
| 4 - 6 | 13 | Less than 6 | 34 (= 21 + 13) |
| 6 - 8 | 7 | Less than 8 | 41 (= 34 + 7) |
| 8 - 10 | 5 | Less than 10 | 46 (= 41 + 5) |
| 10 - 12 | 4 | Less than 12 | 50 (= 46 + 4) |
