Profile of Carl Friedrich Gauss & History of Normal (Gaussian) Distribution

Abstract

The importance of the normal distribution as a model of quantitative phenomenon in the natural and behavioral sciences is due to the central limit theorem. Many physiological measurements and physical phenomenon (Like noise) can be approximated well by the normal distribution. While the mechanisms underlying these phenomenons are often unknown, the use of the normal model can be theoretically justified by assuming that many small, independent effects are additively contributing to each observation
