What is a Quartile?
A Quartile is a type of quantile, the intervals used in defining ranges in probability density functions of continuous random variables. In simple terms, a Quartile is the defining line between intervals within the probability density functions. While Quartiles have no inherent value or transformational properties, they are defined by a discrete value. Unlike a quantile that is defined by the area of an interval, a Quartile is defined by a discrete value.

Quartiles and Machine Learning
As a subset of probability density functions, quartiles are often used in neural networks and machine learning functions. For example, if one is using a neural network to analyze a set of data, it is integral in the creation of a probability density function to define and understand the boundary Quartiles that separate the quantiles containing the possible probabilities of a continuous random variable occurring.
