In mathematics a normal random variable is a variable which possesses the properties randomness and normality. Some mathematicians have suggested this is paradoxical and deny the existence of normal random variables.


The variable X \in N(\mu,\sigma) is a normal random variable of mean \mu and standard deviation \sigma if X normally takes values close to \mu but sometimes randomly takes something else; but \sigma also has some significance in this definition.

A random normal variable can best be explained by a monkey analogy, or better still, by a monkey analogy told on an airship.
