"As in the computation of, for example, standard deviation, the estimation of a quantile depends upon whether one is operating with a statistical population or with a sample drawn from it. For a population, of discrete values or for a continuous population density, the k-th q-quantile is the data value where the cumulative distribution function crosses k/q. That is, x is a k-th q-quantile for a variable X if " - Data quantile

Because outliers have a large effect on machine learning ... WebIn a data set, the median is the 0.5 quantile (or 50th percentile) point meaning that 50% of the data points are less than the value of the median. Similarly, there are other quantile points that can be defined. The 0.1 quantile point (10th percentile) is the value such that only 10% of the data set is smaller than this value.
