exact information it represents. The identifier in computer source code can be bound to a value during run time, and the value of the variable may thus...

Information flow in an information theoretical context is the transfer of information from a variable x {\displaystyle x} to a variable y {\displaystyle...

A random variable (also called random quantity, aleatory variable, or stochastic variable) is a mathematical formalization of a quantity or object which...

In statistics, a categorical variable (also called qualitative variable) is a variable that can take on one of a limited, and usually fixed, number of...

A control variable (or scientific constant) in scientific experimentation is an experimental element which is constant (controlled) and unchanged throughout...

class variable is a variable defined in a class of which a single copy exists, regardless of how many instances of the class exist. A class variable is not...

In mathematics, a variable (from Latin variabilis, "changeable") is a symbol that represents a mathematical object. A variable may represent a number,...

In information theory, the conditional entropy quantifies the amount of information needed to describe the outcome of a random variable Y {\displaystyle...

In computer programming, a global variable is a variable with global scope, meaning that it is visible (hence accessible) throughout the program, unless...
