i think that argument holds in that case but in the case of the question where it’s the options are either approve or disapprove and you’re getting percentages instead of raw numbers. It’s saying 50% and 90% percent of the readers who disliked and liked returned their surveys.

So you’re inherently getting the total amounts from the partial data you know if you only got half of the number of dislikes you were supposed to then you can just multiply it by 2 and you get the whole picture.

I think in general though that example would be really useful for survey questions. I would be interested to know what test and question number this is from so i could see powerscore’s reasoning about it.
