Seriously? Shouldn’t they also have broken out high school by year, or something? Maybe included a radio button for each individual year from kindergarten through law school? No, really, I just can’t imagine how such fine distinctions are useful to anyone. Is someone really looking at this and saying, “Wow, the 7 respondents with some advanced degree work are slightly more likely to say x than the 11 respondents who are currently in advanced degree work! Fascinating! Oh, wait, the margin of error is +/- 37.8%.”
I get that there’s value in collecting more, not less data; I’m a firm believer in asking respondents for their actual ages, actually, instead of for a range — because when you have the actual data, you can put it back together in whatever groupings you want, which may not be the groupings you think make sense before you see the results — but this here is just a mess.
