Draw a histogram for the following data:
| Classes | 59-65 | 66-72 | 73-79 | 80-86 | 87-93 | 94-100 |
| Frequency | 10 | 5 | 25 | 15 | 30 | 10 |
Solution:
| Classes | Classes after adjustment | Frequency |
| 59-56 | 58.5-65.5 | 10 |
| 66-72 | 65.5-72.5 | 5 |
| 73-79 | 72.5-79.5 | 25 |
| 80-86 | 79.5-86.5 | 15 |
| 87-93 | 86.5-93.5 | 30 |
| 94-100 | 93.5-100.5 | 10 |
Represent classes on x-axis and frequency on y-axis :
