Quantile vs. Quartile

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.

Quartilenoun

(statistics) Any of the three points that divide an ordered distribution into four parts, each containing a quarter of the population.

Quartilenoun

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

Quartilenoun

Same as Quadrate.

Quartilenoun

(statistics) any of three points that divide an ordered distribution into four parts each containing one quarter of the scores

Quartilenoun

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

Quartilenoun

each of the three values of the random variable which divide a population into quartiles.

Quartile

In statistics, a quartile is a type of quantile which divides the number of data points into four parts, or quarters, of more-or-less equal size. The data must be ordered from smallest to largest to compute quartiles; as such, quartiles are a form of order statistic.
