Weighted item nonresponse rates ranged from 0 to 1 percent for all items. Imputation for item nonresponse was not implemented. Estimated totals using nonimputed data implicitly impute a zero value for all missing data. These zero implicit imputations will mean that the estimates of totals will underestimate the true population totals. The total number of enrollments in all distance education courses was missing for 5 cases in the sample. For college-level, credit-granting courses, the number of enrollments in courses at both levels was missing for 5 cases in the sample, and the number of enrollments in undergraduate and graduate courses was missing for 11 cases in the sample . The total number of different distance education courses was missing for 8 cases in the sample. For college-level, credit-granting courses, the number of courses at both levels was missing for 7 cases in the sample, the number of undergraduate courses was missing for 11 cases in the sample, and the number of graduate courses was missing for 10 cases in the sample.
