Just my observation coming from a math/statistics double major.
NO statistics required in this situation. The oil filter didnt fit. Yes SS=1 but I'll bet $$ to donuts that every 4967 on my local walmart shelf does not fit. If I wasnt heading to FLA tomorrow Id measure the OEM toyota/denso filter that came on the car from Japan and the Fram and a Wix and report the findings. This would be a mesurement of distance from the plane of the gasket surface to the 1st thread in the baseplate hole.
Statistical methods simply is the study of observed correlation of significant variables and the interpretation of such.
I think that you have pre-concluded which variable has affected the outcome, which is a big violation in statistical studies.
But, that's MY observation of the last 2 pages of posts and I am 95% confident in that interpretation.
Simple logic worked this time - I suppose it depends if you are RESULTS focused or just like to make flowery powerpoint presentations
I've learned that most people's simple logic is, well, simple.
Especially engineers.
Presentations have nothing to do with statistical theory, for what it's worth.
I once did a project that resulted in a correlation between city urban crime and the amount of doctors. I was somewhat amazed that the other dozen or so variables (prisons, education, etc) did not affect the outcomes. Simple logic would have pre-concluded that those other variables would have indeed been correlated, but I would have been wrong. It's made me question what other "logical" conclusions I've come to in my decision making and attempt to think outside of my own limitations.
