P-Curve : P-Hacking Your Way To Fame | Part 6 of 6

This is the last video of a series of videos on p-hacking, what it is, and why it’s so dangerous for science. I give a pretty detailed high-level explanation of p-hacking in the first video in this series, so if you’re not familiar with the idea, please have a look there first. I’ll put a link to that video below. But in a few seconds, researchers are motivated to get what’s called a p-value to be below a threshold of .05. If they do that, their findings are considered meaningful and they can typically publish their results. If they don’t, well all their work is largely wasted. And to get those p-values below .05, there are some very dubious and unethical approaches they can take. In this video, we’ll shift away from how p-hacking works to how to detect it using a tool called a p-curve.

Welcome to Data Demystified. I’m Jeff Galak and today we’ll dig deeper into p-hacking so that you can understand how to spot it when you see research results and avoid it when you do the research yourself. In this video we’re going to build the intuition for how a brilliant p-hacking detection tool called the p-curve works and why it’s a powerful tool to thwart this set of bad research practices.
