In the formal mathematical language of measure theory, a random variable is defined as a measurable function from a probability measure space (called the sample ...

A random variable may be defined as a specification or description of a numerical result from a random experiment. The value itself is called an observation.

Random Variable is a continuous or discrete variable whose value depends on all the possible outcomes of a random experiment. Understand random variables ...

A random variable is a rule that assigns a numerical value to each outcome in a sample space. Random variables may be either discrete or continuous. A random ...

A random variable is a variable whose value is unknown, or a function that assigns values to each of an experiment's outcomes.

Random Variables. A random variable, usually written X, is a variable whose possible values are numerical outcomes of a random phenomenon.
