Octile vs. Quartile — What's the Difference?

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

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.

A subset thus obtained.

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

(astronomy) An octant.

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

Same as Octant, 2.

Any of the values that separate each of these groups.

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

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

Same as Quadrate.

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