Percentile( <List of Numbers>, <Percent> )
Let P equal the given Percent.
Returns the value that cuts off the first P percent of the list of numbers, when the list is sorted in ascending order. Percent must be a number in the interval 0 < P ≤ 1.
Example: Percentile({1, 2, 3, 4}, 0.25) yields 1.25.


Note: The commands Quartile and Percentile use different rules and do not always return matching results.
Example: Q1({1, 2, 3, 4}) yields 1.5 whereas Percentile({1, 2, 3, 4}, 0.25) yields 1.25.
