Abstract in brief

  • Post hoc power analysis involves evaluating the statistical power of a study after the data has been collected and analyzed, which is often requested by journals for published studies.
  • The report examines whether post hoc power analysis provides meaningful and useful information, especially when based on the same data used for the original results, and questions its reliability in this context.
  • Monte Carlo simulations are employed in the study to test how well post hoc power analysis performs, helping to determine if it offers accurate insights into a study's ability to detect significant effects.]

@IvansCat1 @christoph_rothe Deshalb gibt es ja die sog. N(opt.) Formeln (Cohen). Sie geben als Studienleiter eine für Sie wiss. relevante Effektgröße vor, definieren Power und Alpha (bspw. 85% / 5%). Und berechnen daraus N(opt.) für den jeweiligen Test. Stichwort G*Power https://t.co/b6iYc56JUl
