Cumulative Frequency Table (Ungrouped Data)
The following table gives the frequency distribution of marks obtained by 28 students in a particular test.
| Marks | 30 | 31 | 32 | 33 |
| Frequency | 5 | 7 | 10 | 6 |
Construct a cumulative frequency table for the given data.
Solution:
| Marks | Frequency | Marks less than | Cumulative Frequency |
| 30 | 5 | 30 | 5 |
| 31 | 7 | 31 | 5 + 7 =12 |
| 32 | 10 | 32 | 12 + 10 =22 |
| 33 | 6 | 33 | 22 + 6 =28 |

Cumulative Frequency Table (Grouped data)
The following table gives the frequency distribution of mass of 40 objects.
| Mass (g) | 10–14 | 15–19 | 20–24 | 25–29 | 30–34 | 35–39 | 40–44 |
| Frequency | 3 | 4 | 10 | 12 | 6 | 3 | 2 |
Construct a cumulative frequency table for the given data.
Solution:
| Mass | Upper class boundaries | Frequency | Mass less than | Cumulative Frequency |
| 10 – 14 | 14.5 | 3 | 14.5 | 3 |
| 15 – 19 | 19.5 | 4 | 19.5 | 3 + 4 = 7 |
| 20 – 24 | 24.5 | 10 | 24.5 | 7 + 10 = 17 |
| 25 – 29 | 29.5 | 12 | 29.5 | 17 + 12 = 29 |
| 30 – 34 | 34.5 | 6 | 34.5 | 29 + 6 = 35 |
| 35 – 39 | 39.5 | 3 | 39.5 | 35 + 3 = 38 |
| 40 – 44 | 44.5 | 2 | 44.5 | 38 + 2 = 40 |
