This is merely a parallel to the much more comprehensive Sloan-C 'Online Nation' and only covers 77 (out of 215) state universities and land grant colleges - as opposed to 2504 (out of 4491) in the Sloan-C survey last month
Also of particular note is that for this survey the target respondent was specifically the president or chancellor of the college or university rather than the chief academic officer; that alone may largely account for the discrepancy in the response rate (35.8% and 55.8%) and partially for slight inconsistencies in the data. At least with Sloan-C we get actual numerical data in tables as well as graphs; here we get the inherent vagueness of bar charts only and almost no precise numbers to kick around
