Fractile vs. Quantile

Fractilenoun

(statistics) The value of a distribution for which some fraction of the sample lies below.

Fractileadjective

Describing the quality of a sedimentary stone as it relates to the sediments to cohesively bond without fracturing.

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.
