The argument of the cumulative distribution function corresponding to a probability of either 1/4 (first or lower quartile) or 3/4 (third or upper quartile); (of a sample) the value below which occurs a quarter (first or lower quartile) or three-quarters (third or upper quartile) of the observations in the ordered set of observations

A quantile that separates one quarter of the values in a distribution from the remaining three quarters
One of a set of numbers (a quantile) on the random-variable axis that divides a probability distribution into four equal areas The three quartile points that lie between the extremes of the distribution are designated as Q1, Q2, Q3 and are defined in terms of the distribution function F(x) as follows: Thus, Q2 coincides with the median In empirical relative frequency tables, the quartiles are estimated by interpolation The interquartile range 2Q is the distance from Q1 to Q3; half of this distance Q is called the semi-interquartile range (or quartile deviation) and is sometimes used as a crude measure of variability or spread
