Percentiles
Percentiles are values that divide a set of observations into 100 equal parts.
The percentile rank is the proportion of values in a distribution that a specific
value is greater than or equal to. For example, if an individual received a mark of
95% on a math test and that mark was greater than or equal to the marks of 88% of
students then that mark would place that individual in the 88th percentile.
