A quiz:

What statistical concept is used in these design activities?

• DOE (design of experiments)
• Sampling 
• Test results analysis 
• Gage R&R studies 
• Test method validations 
• SPC (with some rules in monitoring changes in a process)

 If you answered, "Hypothesis Testing", you're right on!

Even if you’re not really into statistics, there’s still basics that we should learn and understand, especially in design engineering. 

One of those basics is hypothesis testing. So much of our decisions about whether a design is good or not good (or good enough) is based on this concept. It will fundamentally change how you look at design activities – so much so, it’s a responsibility to understand it.

The podcast blog for this episode includes links to videos to introduce or refresh you on this fundamental topic.
