Detecting p-hacking

WebMay 16, 2024 · Power can be quite low, depending crucially on the particular -hacking strategy and the distribution of actual effects tested by the studies. We relate the power of the tests to the costs of -hacking and show that power tends to be larger when -hacking is very costly. Monte Carlo simulations support our theoretical results. Some parts of this ... WebFor this reason, p-hacking is considered to be highly unethical. How to detect P-hacking. P-hacking is particularly insidious because it can be so hard to detect.
