I found it and will look. thank you!
Yeah, it’s like.. .I’m ok when I can verify in some fashion, look at the result, have something else to compare it to/ contrast it with, and then I can feel confident in it.
For example, you want to sift through a large amount of data to find groupings but you don’t know what to group.
So you try various methods of grouping until you get a result that seems to have decent separations.
So now that you have these distinctions, how do you know if they’re any good – or even what they mean?
