WebbThe Quantile Function In general, to deﬁne the quantile which corresponds to the fraction p, use linear interpolation between the two nearest p i. If p lies a fraction f of the way from p i to p i+1 deﬁne the pth quantile to be: Q(p) = (1−f)Q(p i)+fQ(p i+1) As special cases, deﬁne the median and quartiles by: Median: Q(.5) Lower ... WebbIn 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.
