Quantile vs. Quintile — What's the Difference?

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.

The astrological aspect of planets distant from each other by 72° or one fifth of the zodiac.

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.

Any of the groups that result when a frequency distribution is divided into five groups of equal size.

(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.

Any of the values that separate each of these groups.

(statistics) Any of the quantiles which divide an ordered sample population into five equally numerous subsets.

(by extension) A subset thus obtained.

(astrology) An aspect of planets that are distant from each other by one fifth of a zodiac (72°)

The aspect of planets when separated the fifth part of the zodiac, or 72°.
