## Why is normal distribution important in statistics?

**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. A random variable with a Gaussian**distribution**is said to be normally distributed and is called a**normal**deviate.
