I have written a series of posts on the new IPEDS data, including two that showed how this data seems to be quite different from the pervasive Babson Survey Research Group (BSRG) data (formerly known as the Sloan Survey). In particular, there were two findings, one on the number of students taking online courses:
And no, there aren’t 7.1 million [from Babson] US higher ed students taking at least one online course. There are closer to 5.5 million [from IPEDS] as of Fall 2012.
and one on the number of institutions offering online education:
The big difference that should be obvious is that the Babson data shows less than half the number of institutions with no online offerings than the IPEDS data – 15% compared to 31%.
Who has an online offering?
I have been in contact with Jeff Seaman, one of the two authors of the BSRG reports, to get his analysis on the differences, including sharing my spreadsheets used for analysis of the two data sets. Jeff has graciously reviewed the data and provided the following analysis of why BSRG data is so different from IPEDS data.
