**Explain QUANTILE, QUARTILE:** When you divide a set of sorted values into groups that each have the same number of values (for example, if you divide the values into two groups at the median), each group is known as a quantile. If there are four groups, we call them quartiles, which is a common way to divide values for discussion and analysis purposes; if there are five, we call them quintiles, and so forth. See also median.
