网页The normal distribution is a continuous probability distribution that plays a central role in probability theory and statistics. It is often called Gaussian distribution, in honor of Carl Friedrich Gauss (1777-1855), an eminent German mathematician who gave important contributions towards a better understanding of the normal distribution.
