Abstract
In this paper, we evaluate the quality of survey data collected by the Malawi Diffusion and Ideational Change Project by investigating four potential sources of bias: sample representativeness, interviewer effects, response unreliability and sample attrition. We discuss the results of our analysis and implications of our findings for the collection of data in similar contexts.
