Methodological Briefs Quasi-Experimental Design and Methods: Methodological Briefs - Impact Evaluation No. 8 AUTHOR(S) Howard White; Shagun Sabarwal Published: 2014 Methodological Briefs Quasi-experimental research designs, like experimental designs, test causal hypotheses. Quasi-experimental designs identify a comparison group that is as similar as possible to the intervention group in terms of baseline (pre-intervention) characteristics. The comparison group captures what would have been the outcomes if the programme/policy had not been implemented (i.e., the counterfactual). The key difference between an experimental and quasi-experimental design is that the latter lacks random assignment. + - Cite this publication | No. of pages: 16 | Thematic area: Ethical research, Knowledge management | Tags: comparative analysis, experiments, programme evaluation, research methods × COPY BIBLIOGRAPHIC CITATION Howard White; Shagun Sabarwal 2014 Quasi-Experimental Design and Methods: Methodological Briefs - Impact Evaluation No. 8. , pp. 16.
