Continuing with the favorite fact from Chapter 8 of my textbook. While writing this I did some digging into where heuristics of sample sizes come from. I found they are miscitations of miscitations of miscitations (like this example) https://lakens.github.io/statistical_inferences/power.html#heuristics
Don't use heuristics. Have a real sample size justification justification.
@lakens thank you for sharing your book! My students were just asking about sample size justification and I can see you’ve written a whole chapter on this. Thanks for creating this resource.
@h_shawberry It is largely a reused open access paper that is published in Collabra earlier this year (and already cited 300 times!), but the book chapter will always be more up to date and has questions at the bottom, so better for teaching.
@h_shawberry It is very long, as my own students kindly pointed out when I used it in one of my own courses :) So maybe pick some sections that they might need the most ;)
