Product quality assessment rating
How can product quality assessment be represented statistically? E.g, out of 8 pallets of a particular product produced in an 8 hours shift, how can the quality of this product be represented statistically?

Dear James,
It's important to make clear definitions, before applying statistical analyses:
- Your process needs to be controlled and it's necessary to know what parameters are already measured
- The quality of the particular product has to be well defined
- The product sampling method needs to be well described (and followed)
Kind regards,

I interpret "represent" as "estimate". I assume a random sample.
The simplest answer is by the Average Value plus a confidence level.
Not so easy if it's smell of course. :smile:
Also see this post whose middle file has many examples of "quality" -
