Data Limitations

All survey data collections involve potential sources of error. The monitoring evaluation's mail survey is no exception. While data entry and coding errors were minimized through standard data quality assurance procedures (e.g., data entry with verification), other potential sources of error were more difficult to address and should be kept in mind by readers reviewing the survey data.
