For more than 35 years we have conducted hundreds of surveys across a variety of research areas with thousands of respondents. PPRI has the capability to design and test any kind of survey instrument. We create web-based survey questionnaires and instruments programmed for telephone interviewing, in-person field interviews and can offer a customized, multi-modal approach. 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 survey data collection, PPRI is experienced in analyzing survey data and bringing that analysis to bear on policy and related questions. We specialize 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.
