I'm reading about different kinds of statistical analysis in user studies and
every few paragraphs starts with "However, it is not always straightforward to ..." and then chains through a few things comparing tradeoffs until just going "usually we just aggregate it all together" and then back to "However," and into another layer of measuring and aggregating
I'm afraid the rest of this textbook is just going to be an ever-deepening rabbithole of measuring stats about stats about stats
