Tons of Quality Templates - Six sigma meets Excel and spawns a monster!

Amazing collection of Six Sigma and quality Excel templates. Someone has put some serious effort into making some full-featured forms.

Let's say you don't want to shell out for the latest version of Minitab. You're sure to find a simple Excel hypothesis test that you can download from the internet. And then you come across this site:

In the side bar list of Excel quality templates, you will find not just one simple T test, but the T test, the F test, Chi squared test and Mann Whitney Rank sum test!

Four! hypothesis testing templates for your six sigma projects.

As a six sigma blackbelt, I once learned the formulas for calculating these tests. Then I promptly forgot them and depended on Minitab to do all the number crunching for me. I'm more of a results guy, then a theoretical numbers man. But someone put a lot of work into these templates and I commend them for that.

And there's more. A lot more.

Not only do we have the aforementioned hypothesis tests, there's gauge R & R templates (variable and attribute), a 3 factor DOE form, probability analysis templates (z tables etc), capability studies, regression analysis and much more.

Really. This is definitely a one stop shop for your quality forms and calculations.

My only disclaimer is that there's so much here that I haven't checked to see if all the calculations are accurate. And as long as I still have a day job and a life in general, I'm not going to be able to spend a few years doing that. So use at your own risk and post here if you have the energy and time to verify the forms for accuracy.  


  1. It sounds great, downloading it and see how good is it

  2. Very good post, I was really searching for this topic, as I wanted this topic to understand completely and it is also very rare in internet, that is why it was very difficult to understand.

    Thank you for sharing this.
