Six-Sigma Training Book內容提要:
First introduced by French mathematician Abraham DeMoivre in 1733.
Made famous in 1809 by German mathematician K.F. Gauss when he also developed a normal distribution independently and used it in his study of astronomy.
As a result, it is also known as the Gaussian distribution.
During mid to late nineteenth century, many statisticians believed that it was “normal” for most well-behaved data to follow this curve.
正態分布易於理解, 具有特性, 統計學提供了許多基於正態分布的強有力的分析方法來幫助人們做決定.
因此, 我們通常會試圖用正態分布去近似模擬其它分布 (如可能) 或轉化數據以“使”它遵從正態分布.
它是分析過程能力的首選分布形式.
