Internet Learning Journal Notably, the difference in the set of institutions examined is important, and is representative of the breadth of institutional types and settings in the U.S. Some of these are large urban, some are rural, some are multi-campus, and some are individual campus organizations. By examining historical persistence outcomes and data feature variance within individual institutions rather than across institutions, the differences in likely success rates between selective institutions and access-oriented institutions are eliminated. Data Sources Details on the institutions included in this study, including their overall student data count and historical overall undergraduate persistence rate, are shown in Table 1. The set of historical terms for each institution aligns with the 2016 calendar year and the semesters or quarters that would be so included. The overall undergraduate historical persistence rates range from 62.5% for one of the 2-year institutions to a high of 95.8% for one of Table 1: Institution Detail 4-YEAR INSTITUTIONS Descriptor Study N Historical Persistence Rate A 57,425 88.80% B 93,211 85.70% C 125,988 95.80% D 16,607 86.90% 2-YEAR INSTITUTIONS Descriptor Study N Historical Persistence Rate A 82,000 62.5% B 48,812 64.9% C 17,908 67.9% D 77,455 74.3% PROPRIETARY INSTITUTIONS Descriptor Study N Historical Persistence Rate A 48,000 89.7% B 127,979 83.4% C 92,000 78.3% TOTAL 11 787,385 10
