This graph, which has been fairly widely circulated (along with considerable debate about it’s legitimacy) is from the Wellesley/MIT student paper Counterpoint.  The original article is no longer online, so it’s hard to say how scientific it was, but everything I can gather suggests that it was at least based on an actual survey.  For me, the points of verisimilitude are the relatively shallow slope of the curve, the fact that “undecided” was included as a major, and the duplications of 83% (10 in 12) and 50%.
Also, the order makes sense to me, but YMMV.
