@rbutler Most of the exams are not written by people who are trained educators so the questions can be pretty oddly worded and of course as you can see completely wrong. Chris Seider actually wrote my tests or at least the better part of them and did a nice job.
@Ddeisle There are tons of exams out there and certification is being sold by every…[Read more]

@katiebarry Hi Katie, Hope all is well. I was going to respond to this until I reread everything and how old it is. By now, it is probably a failed deployment like so many in Healthcare LOL. I’m big into pharma and healthcare now and know of its challenges.

@RobertButler Hi Robert. I tossed this thread to you because I missed all your great responses. Thanks for jumping in. Hope all is well. Not much action or volume here any more like the old days. Except for you and Carnell.

Discussion ensues better if you post the question and state the reasoning for the answer and then you can get neat feedback.

@Ddelisle You can certainly post your questions. Remember: The more information you provide, the better. What do YOU think the answer is? What was your process for arriving at the answer? Do you have an idea about what you might be tripping over or why the company’s provided answer is wrong/doesn’t match yours?

@lausto @RobertButler While the problem you are asking is an interesting stat question I would wonder why a customer would even ask such a question. What are the specs for the part coating weight? I would assume that your customer would want all parts to be in spec not the average of parts to be in spec. You can have parts equally varying from…[Read more]

One can be utilized but not productive. I’d be open to learning/hearing why this has merit.
It’s sort of like a production line being “up/running” but only running at 10% of capacity–it’s utilized but not productive.

@vicbernie999 @mike-carnell You are correct in stating that the classical texts teach that the assumptions of the t-test are independence, normality and equal variance. Independence is important to determine. If not, the advice about using the paired t-test is good. Minitab gives you the option to choose equal variances or unequal variances so…[Read more]
You will need to invest the time/money if truly want to understand your gage’s variation relative to the process and specification range.
However, you can get away with just doing 2 independent measurements by each of your 3 operators if you do the 10 parts–it’s a long discussion why this CAN be done in cases for expensive and time consuming…[Read more]
@Vicbernie999 The list of hypothesis tests you listed may have come from a flow chart Miguel Hernandez and I created when we were teaching hypothesis testing in Europe (there is an article on iSS somewhere about it). That flowchart was created to explain what we were teaching. There is no point where it says it is an excusive list of hypothesis…[Read more]
