Statistics Lesson #3: Randomized Experiments & Observational Studies

This video is for my College Algebra and Statistics students (and anyone else who may find it helpful). I define a randomized experiment, show a couple of examples, and define some important vocabulary related to experiments. Then I define an observational study, give an example, and discu

Observational Studies - Causal Inference

Today I talk about how observational studies are great examples of when causation does not equal association by visiting a real world example. The next videos will explore how we extract causal information from observational studies
