Description

In this special episode of Quality during Design Redux, we're pulling episodes from our archive about test results analysis.

In our Season 1 - Episode 93  titled "The Fundamental Thing to Know from Statistics for Design Engineering", we talked about hypothesis testing: how it is used for lots of data analysis techniques.

The next 4 episodes of this QDD Redux are taking the next steps.
_________________________________________
When trying to fit a probability distribution to quantitative results, sometimes the normal probability doesn't fit. Minitab has a wealth of distributions to pick from. Do you just pick whichever one Minitab tells you fits the best? Maybe not. Just because the distribution fits your data doesn't mean it's a good one to use. We review my top 3 distributions for product testing and some other ones that come up but may not be appropriate to use. We'll also share what you need to think about when picking a distribution.
The podcast blog includes useful links.
