    Hi Experts,
    I am into Quality for the past 2 yrs but i am having difficulty learning six sigma as i am not strong in basic statistics. Should I start from the basics? If so, how? Kindly help so that it does not become too late for me to learn…
    Thanks,
    Suresh B S

    Mr. BS,
     
    Stats only make up 10%* of what most Six Sigma dorks do.  Some might push 50%**.  The project management, facilitating, interviewing, training, motivation and other “soft” skill is the bread and butter*** of what they do.
     
    Learn a few basic stat phrases**** and the rest you will learn as necessity demands.

    I would go as far as 20%.  Although Analyze Phase goes quickly, it is still 1/5 of the project.  Also it helps display where to focus your attention of improvement.

    I’m ok with that.  Let’s say somewhere between 10 and 20% (sample size = 2).
    Variable N N* Mean SE Mean StDev Minimum Q1 Median Q3 Maximum
    C1 2 0 15.00 5.00 7.07 10.00 * 15.00 * 20.00

    Suresh B S,
    We rarely start our Black belts with no statistics in their background with the basics. Central Composite Designs works much better as a starting point. If you follow that with Multiple Linear Regression they will catch right on.
    There is a reason that the basics are called the basics.
