Mildly Interesting

~~There are some errors in the "correct" numbers For example, note that the respondents estimated that 89% of Americans have a high school diploma or higher. Yet the chart says the real figure is 65%. But doesn't that seem odd to you? Do you think on average 35% of people drop out of high school?~~

~~No, the source of this error is that the question is poorly worded. 90% of Americans 25 or older have a college degree. The graphic indicates the poll asked specifically about adults. And it seems the respondents had the correct answer, about 90%.~~

~~I don't know where they get the figure that only 65% of adults have a high school degree. My best estimate is that they mixed up "the percentage of adults with a high school degree" and "the percent of people with a high school degree." The latter would count all current K12 students, as they obviously don't have their diploma yet.~~

~~This is one item that really stood as an obvious and glaring error. And if I can see this one, I wonder if other numbers in either the 'correct' responses or the respondents' results are just due to poor or incorrect phrasing/interpretation of questions.~~

I have two master's degrees, have spent years teaching undergraduate engineering courses, am working on a dual-major PhD in engineering...and I...apparently...cannot read a plot.
