Experimental data Today I want to talk about two-sample hypothesis testing, or A/B testing in data science parlance. This topic has been on my mind a lot as of late because I’m planning on leaving academia for data science, and that means I may also be transitioning from analyzing survey data to running experiments on unstructured, “big” data. Because academia and business have different goals and resources available to them, the methods they use are also different, even when approaching a similar problem.
