Percentile

In descriptive statistics, a percentile is any of the 99 values that divide the sorted data into 100 equal parts, so that each part represents 1/100th of the sample or population.

Thus:

  • The 1st percentile cuts off lowest 1% of data
  • The 98th percentile cuts off lowest 98% of data

Calculating percentiles

See quantile for methods. The percentile is calculated as the 100-quantile.
