Video lecture 16: Why meta-analysis is policy-relevant: a video lecture by Hugh Waddington
Speaker: Hugh Waddington, Senior evaluation specialist, 3ie
In this How-To video, Hugh Waddington (3ie) explains why meta-analysis is one of the most appropriate methods for decision makers to use in policymaking. Meta-analysis is a quantitative statistical analysis of several separate but similar experiments or studies in order to test the pooled data for statistical significance. Using examples from 3ie studies on micro-credit and land reform programmes, Hugh explains how meta-analysis can help investigate a wide variety of questions, as long as there is a reasonable body of primary research studies.
