Stochastic variables are prominent concepts in various fields such as physics, economics, finance, and engineering. They are entities whose values have a probability distribution that integrates possible random events. The term stochastic variable is used interchangeably with random variable, chance variable, and probabilistic variable in some technical contexts. Similarly, in statistics, some synonyms for the stochastic variable are uncertain variable, uncertain quantity, and chance quantity. Within mathematics, the terms probabilistic magnitude, uncertain magnitude, and random coefficient are also used to refer to the concept of stochastic variables. These various synonyms used in different fields imply a common concept of unpredictability and randomness in the variability of an event.
