What is Six Sigma ? 6 Sigma ? Why are we saying Six Sigma ? Six sigma Methodology?

[@goldaila8132]

Please check and correct. 6 SIgma is equal to +/- 6 sigma.

Correct, this video is wrong about the definition of Six Sigma. Six Sigma has to do with the nearest spec limits being 6 standard deviations from the average (mean), which is not discussed in the video. The video is describing standard deviations and the normal distribution rules, which are correct, and it is also correct that +/- 3 standard deviations on each side of the average is equal to a span of 6 standard deviations, but that is not the same as six sigma (a common mistake people make).
Here is where I've described it in another video: ua-cam.com/video/IHC6YNFQ38w/v-deo.htmlsi=yLSgK9jgEeJZ6MRP&t=60
