Percentile vs. Quantile

Percentilenoun

(statistics) Any of the ninety-nine points that divide an ordered distribution into one hundred parts, each containing one per cent of the population.

Percentilenoun

(statistics) Any one of the hundred groups so divided.

Percentilenoun

(statistics) any of the 99 numbered points that divide an ordered set of scores into 100 parts each of which contains one-hundredth of the total

Percentilenoun

each of the 100 equal groups into which a population can be divided according to the distribution of values of a particular variable.

Percentilenoun

each of the 99 intermediate values of a random variable which divide a frequency distribution into 100 such groups

Percentile

In statistics, a percentile (or a centile) is a score below which a given percentage of scores in its frequency distribution falls (exclusive definition) or a score at or below which a given percentage falls (inclusive definition). For example, the 50th percentile (the median) is the score below which (exclusive) or at or below which (inclusive) 50% of the scores in the distribution may be found.

Quantilenoun

(statistics) One of the class of values of a variate which divides the members of a batch or sample into equal-sized subgroups of adjacent values or a probability distribution into distributions of equal probability.

Quantilenoun

each of any set of values of a variate which divide a frequency distribution into equal groups, each containing the same fraction of the total population.

Quantilenoun

any of the groups so produced, e.g. a quartile or percentile.

Quantile

In statistics and probability, quantiles are cut points dividing the range of a probability distribution into continuous intervals with equal probabilities, or dividing the observations in a sample in the same way. There is one fewer quantile than the number of groups created.
