Let $D$ be a finite collection of data regarding some quantitative variable.

Let $D$ be divided into precisely $100$ class intervals.

A $P$th percentile is a value in the interval defined by the $P$th class such that:

$\dfrac P {100}$ of the data in $D$ fall at or below the value chosen

$1 - \dfrac P {100}$ of the data in $D$ fall at or above the value chosen.
