Introduction
Welcome to the calculators home page of PowerAndSampleSize.com!
Not much to go over here. Our calculators are pretty self-explanatory. At the top of each calculator's page you'll find a form and a graph. Enter values in the form, then you can examine the graph to learn how sensitive the required sample size is to the input values you've provided
You can navigate the calculators using the menu to the left. There, you'll also find links to further documentation, including usage instructions, references, and a validations page comparing our calculators' output to published results.
Below each calculator you'll find a description of the calculator and the situations in which it may be useful. We've also included the underlying mathematical formula, R code so you can implement custom calculations, and one or more literature references that give further details.
Please feel free to comment below; comments are also available at the bottom of each calculator's page.
