Imputation
The project team developed and implemented a clear editing strategy that was used to train the editors' team to ascertain good quality data. The strategy consists in:
· Collecting all filled in questionnaires from the fieldworkers on daily basis.
· Checking each questionnaire for completeness of all sections and ascertaining that all question items were precisely filled in.
· Returning back all questionnaires with missing responses or doubtful information.
· Checking the accuracy of some of the data by phone interviewing the respondent by the project coordinator or the supervisor.
