This special episode is a rebroadcast of AMA #30, now made available to everyone, in which Peter and Bob Kaplan dive deep into all things related to studying studies to help one sift through the noise to find the signal. They define various types of studies, how a study progresses from idea to execution, and how to identify study strengths and limitations. They explain how clinical trials work, as well as biases and common pitfalls to watch out for. They dig into key factors that contribute to the rigor (or lack thereof) of an experiment, and they discuss how to measure effect size, differentiate relative risk from absolute risk, and what it really means when a study is statistically significant. Finally, Peter lays out his personal process when reading through scientific papers.
