Using Mixed Methods to Improve the Quality and Relevance of Impact Evaluation
It is now widely recognized that a rigorous, policy-relevant impact evaluation embeds the counterfactual analysis of impact in a wider analysis of the underlying program theory (theory of change) of the intervention, also referred to as causal chain analysis. Unpacking the causal chain requires a combination of factual and counterfactual analysis. The seminar will present examples of causal chains. The types of data collection and analysis – both quantitative and qualitative – to analyze the different links in the chain will be discussed. A major challenge in mixed methods is to truly integrate quantitative and qualitative approaches.
