Calculate More than type Cumulative frequency table from the following grouped data
| Class | Frequency |
| 15 - 20 | 3 |
| 20 - 25 | 9 |
| 25 - 30 | 14 |
| 30 - 35 | 20 |
| 35 - 40 | 35 |
| 40 - 45 | 9 |
| 45 - 50 | 6 |
| 50 - 55 | 2 |
| 55 - 60 | 2 |
Solution:| Class | Frequency |
| 15 - 20 | 3 |
| 20 - 25 | 9 |
| 25 - 30 | 14 |
| 30 - 35 | 20 |
| 35 - 40 | 35 |
| 40 - 45 | 9 |
| 45 - 50 | 6 |
| 50 - 55 | 2 |
| 55 - 60 | 2 |
More than cumulative frequency can be obtained by adding to the other frequencies in the reverse order.
| Class | Frequency | More than type | Cumulative Frequency |
| 15 - 20 | 3 | More than 15 | 100 (= 97 + 3) |
| 20 - 25 | 9 | More than 20 | 97 (= 88 + 9) |
| 25 - 30 | 14 | More than 25 | 88 (= 74 + 14) |
| 30 - 35 | 20 | More than 30 | 74 (= 54 + 20) |
| 35 - 40 | 35 | More than 35 | 54 (= 19 + 35) |
| 40 - 45 | 9 | More than 40 | 19 (= 10 + 9) |
| 45 - 50 | 6 | More than 45 | 10 (= 4 + 6) |
| 50 - 55 | 2 | More than 50 | 4 (= 2 + 2) |
| 55 - 60 | 2 | More than 55 | 2 |
