Normal distribution - Wikipedia
A random variable with a Gaussian distribution is said to be normally distributed, and is called a normal deviate. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known.

Normal Distribution (Bell Curve): Definition, Word Problems
What is a Normal distribution? The normal distribution, also called the Gaussian distribution, de Moivre distribution, or “bell curve,” is a probability distribution that is symmetric about its center: half of data falls to the left of the mean (average) and half falls to the right.
