The article fails to deal with selection bias. It never establishes that the populations that enroll in online courses are sufficiently similar to the populations that enroll in traditional courses that such things as attrition rates, etc., can be directly compared.

It seem to me that one of the principal reasons someone would takes an online course is if thier schedule won't allow them to take traditional college courses(i.e. works full time and has kids at home). Should it then surprise you that these are the people with the highest attrition rates.
