How do I figure out percentiles?

When you know the percentile of a specific value, you can easily calculate the percentile rank using the percentile rank formula:

1. Percentile rank = p / [100 x (n + 1)]
2. Percentile rank = (80) / [100 x (n + 1)]
3. Percentile rank = 80 / [100 x (25 + 1)]
4. Percentile rank = 80 / [100 x (26)]
