In preclinical biomedical research, it is common practice to conduct exact replications with the same sample sizes as those used in the initial experiments. Such replication attempts, however, have lower probability of replication than is generally appreciated. Indeed, in the common scenario of an effect just reaching statistical significance, the statistical power of the replication experiment assuming the same effect size is approximately 50 KW - Animals KW - Bayes Theorem KW - Biomedical Research: methods KW - Biomedical Research: statistics & numerical data KW - Data Interpretation, Statistical KW - Humans KW - Models, Statistical KW - Probability KW - Publications KW - Reproducibility of Results KW - Research Design: statistics & numerical data KW - Sample Size LB - PUB:(DE-HGF)16 C6 - pmid:30964856 C2 - pmc:PMC6456162 DO - DOI:10.1371/journal.pbio.3000188 UR - https://pub.dzne.de/record/140670 ER -
