Meaning of normal random variable | Babel Free

Definitions

A random variable whose probability distribution is a normal distribution.

Examples

“Since this density function cannot be integrated directly, in order⟳ to find⟳ probabilities involving normal random variables, we must resort to tables giving us various percentile points of the distribution.”

“Although normal random variables are continuous, they are often used to model⟳ discrete quantities.[…]The probability density function of a normal random variable depends on two parameters, denoted μ and σ, which are, respectively, the mean⟳ and standard deviation of the random variable.”

“A special type⟳ of continuous random variable, known as a normal random variable, is studied.[…]We present⟳ the additive property of normal random variables. The percentiles of normal random variables are studied.”
