What is the formula to calculate percentile?
When you know the percentile of a specific value, you can easily calculate the percentile rank using the percentile rank formula:
- Percentile rank = p / [100 x (n + 1)]
- Percentile rank = (80) / [100 x (n + 1)]
- Percentile rank = 80 / [100 x (25 + 1)]
- Percentile rank = 80 / [100 x (26)]
