उत्तर
The data given is raw data.
Ascending order: 0, 1, 2, 3, 4, 5, 6
| Number of children | Tally marks | Frequency |
| 0 | II | 2 |
| 1 | IIII I | 6 |
| 2 | IIII I | 6 |
| 3 | IIII | 4 |
| 4 | III | 3 |
| 5 | III | 3 |
| 6 | I | 1 |
| Total | 25 | |
∴ Tabulating in frequency distribution table we get
| Number of children in family | 0 | 1 | 2 | 3 | 4 | 5 | 6 |
| Frequency | 2 | 6 | 6 | 4 | 3 | 3 | 1 |
