Abstract
This paper presents the steps to conduct a meta-analysis of a set of repeated A/B tests. Repeated A/B testing is common in professional marketing practice. Each test, however, can only be individually evaluated for statistical significance when using basic statistical analysis. A meta-analysis of the same A/B tests provides three useful analytics outputs: an overall treatment effect across all tests, a confidence interval for that effect to assess statistical significance, and a measure of heterogeneity between tests to assess the context variation between campaigns. Meta-analysis is a useful addition to marketing analytics practice.
Keywords: meta-analysis; A/B testing; significance testing; marketing campaign analytics
