Isn't the crux just that, "proper random sampling" can be quite hard. Assumptions are fine in theory, in reality, they can seriously throw us for a loop.

- ip26 6y agoRight, so you really need to review the study's methodology to determine if N = 266 is actually enough or not. I am guessing my original parent did not conduct such a review.
- irjustin 6y agoI'm not sure which side to take on this issue. I think both can be right, but I lean towards agreement with the root comment. Root parent comment is right to question if the N=266 is truly random given the description we do have at hand. You are right to say N=266 could be truly random and we don't have enough information to definitively decide either way. We can't read the study so it's just what we have - saying you have a truly random sample with a group just from Barcelona is extremely hard to accept. I mean even you've got to admit that.
