CQM / CQA Studying for CSSBB

Looking for some help and thoughts.  I am a CQM and CQA and am now studying for the CSSBB and am really struggling with the statistics portion of the study guide.  I am even losing sleep over it.  

If you're asking why I am doing it, my position is now requesting we have it, plus it's a bonus in the workplace.  I already have my project done and approved and have my Green Belt through my company.  

What's the best study guide for the statistics portion?  I have the CSSBB Study Primer from the Quality Council of Indiana as well as the Solution Text.  

I have been in Quality for over 25 years and never used any of those manual formulas so struggling!  Suggestions, thoughts, guidance?  

What's the exam like - how many are actually statistical problems?  I am learning to use my calculator all over again!  LOL!

Any help would be greatly appreciated.

Hi Joy Young‍ - I'm so sorry to not answer sooner! There are a lot of conversations on here about the difficulties of statistics in some of the exams.

The Statistics Division does a get job - https://www.youtube.com/watch?v=obSupUdTjV8

I'll also tag a couple of experts that might be able to assist - Joseph Basala‍ , Duke Okes‍ , Gary Gehring‍, Mindy Hotchkiss

Good Luck!

Joy,

The Analyze phase accounts for roughly 15% of the exam. It contains Hypothesis Testing which most people find to be challenging. While I am sure it varies some with the exact exam configuration, calculations should likely not account for more than 30% of the exam.

I personally find it beneficial to practice statistical problems in parallel with performing them in a statistical software package. This way I can verify quickly if I got the right answer. Also, try to understand the big picture before getting lost in the detail.

In taking the exam, I have found it beneficial to do the exam in multiple rounds. First only answering the questions I know the answer to. Secondly to go through the exam and answer the questions where I know the material is in my reference books. Thirdly work on calculations as these can be the most time-consuming.

Hi Joy:

I passed the exam in 2009 and have not taken it since. If I remember correctly, the statistical focus was on hypothesis testing, reliability mean time before failure, mean time to repair, design of experiments. What was the most beneficial to me was purchasing the CD from the Indiana Council of Quality with the 1,000 question exam. I practiced and answered those questions over and over until it became second hand. The cost is about $70, but is worth its weight in gold. Best of luck.
