In this episode, I explain how to come up with a good question, obtain the background information you need, find research, obtain full texts, organize them, read the different sections of a paper to get the right kind of value out of it, and critically analyze the study design. If you're a beginner, this is really designed for you. If you're more advanced, you'll enjoy the specific examples I give of problems interpreting research studies.
