    Sweety,
    Six in Numbers would be at 6sigma: you would have 3.8 defects for million parts produced.
    Or you can say at 6 six sigma a process/product line could have 3.6 defects a for evey million opportunities.
    Similarly you can have 5 sigma, 4 sigma………
    Not clear what kind of information you are looking at?

    I meant 3.4 defects…… and not 3.8
    Sweety you can find needed literature ont this website so if you go through the content on this wensite that would pretty much answer all your doubts!

    Actually Sweety, to be both more acurate and more interesting in the definition, 6 sigma is the area under the normal curve that is 6 standard deviations away from the mean.  The area of the curve (on one side)remaining 6 standard deviations away is equal to 2 parts per billion, or .0000000002.

    Come on guys.  Does anybody really believe that table ?  How many times do we have to go over this utter nonsense ?
    Sigma levels are meaningless because they depend on the assumption of PERFECT normally distributed data and a 1.5 “shift” “correction” or whatever rubbish.
    BURN THOSE TABLES !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
