Introduction to Normal Random Variables
Introduction to Normal Random Variables
What you’ll learn to do: Use a normal probability distribution to estimate probabilities and identify unusual events.

The normal random variable is the classic bell curve graph that might look familiar. In statistics, the normal random variable is a powerful tool in estimating probabilities in hypothesis testing. Many statistical tests will use this standard random variable, so building a solid understanding of how to work with the normal random variable is critical to building up our statistical tool box.
