rullean replied to the topic The Value of Six Sigma Certification in the forum General 19 years, 3 months ago
But please keep in mind that they are still starting the deployment of Six Sigma in their company. We have experienced this problem where people are questioning the “legality” and “longetivity” of this program.

Hello Janeessa,
I have read somewhere that with this kind of surveys, if you have 1,600 sample size (consider that all 1,600 replied to your survey), you have a + 2.5 % margin of error.

Thank you very much everyone for all your insights. Definitely I would be looking at each one at amazon for their overview and table of contents. So far, I already have Statistical Methods by Cochran, a local book called Applied Statistics for Business, and Introduction to SPC, which is still coming. Thanks once again…
