Guidance Note #3: Introduction to Mixed Methods in Impact Evaluation
This is the third guidance note in a four-part series of notes related to impact evaluation developed by InterAction with financial support from the Rockefeller Foundation.This third guidance note, Introduction to Mixed Methods in Impact Evaluation, starts by explaining what a mixed methods (MM) impact evaluation design is and what distinguishes this approach from quantitative or qualitative impact evaluation designs. It notes that a mixed methods approach seeks to integrate social science disciplines with predominantly quantitative (QUANT) and predominantly qualitative (QUAL) approaches to theory, data collection, data analysis and interpretation. The purpose of doing so is to strengthen the reliability of data, validity of the findings and recommendations, and to broaden and deepen our understanding of the processes through which program outcomes and impacts are achieved, and how these are affected by the context within which the program is implemented. The guidance note also highlights the potential applications and benefits of a mixed methods approach for NGOs.
This guidance note is also available in Spanish and French. Translated versions, along with the other notes in the series and associated webinars are available here: http://www.interaction.org/impact-evaluation-notes.
