Utilizing a dataset with the next values: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
| Worth |
| — |
| 10 |
| 20 |
| 30 |
| 40 |
| 50 |
| 60 |
| 70 |
| 80 |
| 90 |
| 100 |
To calculate Q1, first decide the twenty fifth percentile, which is the Q1 worth. Since there are 10 observations (n = 10), the index is: (10 + 1) / 4 = 2
Q1 = 20
