Re: #98
http://online.wsj.com/public/resources/documents/info-Degrees_that_Pay_you_Back-sort.html shows survey results of median starting pay and mid career pay by college major.
It also shows survey results of 10th, 25th, 75th, 90th percentile mid career pay. Some have much higher variation than others. E.g. the 90th percentile to 10th percentile pay is around 5 for music, but only around 1.9 for physician assistant.
