As you prepare your courses on quantitative methods, consider including a section on statistical power. Here are five readings I like and often recommend. Quantitative Political Science Research is Greatly Underpowered (Arel-Bundock et al.) This paper shows that low power is a real problem—“doing...

It’s helpful to think of statistical power as determined by the ratio , where is the treatment effect and SE is the standard error of the estimate.1 1 Bloom (1995) has a really beautiful paper on this idea. It’s one of my favorites. I also have a preprint on the topic.I like this ratio because it...

Power Rules This post is based on this paper called “Power Rules.” We can think of statistical power as determined by the ratio , where is the treatment effect and SE is the standard error of the estimate. To reason about statistical power, one needs to make assumptions or predictions about...
