In our data-driven environment, new ideas are always put to test, ideally in randomized,  controlled A/B Experiments. However, many interventions require different approaches, for example because we influence existing defined groups instead of truly randomized groups, or we compare different markets to each other.

To approach such challenges, you get creative with many of the following ideas: quasi-experimental designs, adaptive testing designs, penal studies, causal inference techniques, and many more. You will setup, analyze and ultimately validate parametric and nonparametric tests, bayesian methods, correction methods (e.g., propensity scores), hierarchical models, etc., for many different use cases.
