PPRI has the capability to design and test any kind of survey instrument. We create web-based survey questionnaires, mark sense questionnaires, and instruments programmed for telephone interviewing. PPRI researchers also develop programs allowing survey data to be collected on notepad computers in the field with real-time data encryption. In addition, we have the expertise for developing a wide-range of sampling strategies including GIS database utilization to produce cluster samples and maps for in-person household interviewing.
In addition to data collection, PPRI has a great deal of experience in analyzing survey data and bringing that analysis to bear on policy and related questions. Furthermore, PPRI specializes in developing complex sample designs that often require weighting and error estimation procedures that are beyond the usual scope of methods used in more basic or routine surveys.
