One reason is that many results may be selected for drawing inference because some threshold of a statistic like the P-value was crossed, leading to biased reported effect sizes. Nonetheless, considerable non-replication is to be expected even without selective reporting, and generalizations from single studies are rarely if ever warranted. Honestly reported results must vary from replication to replication because of varying assumption violations and random variation; excessive agreement itself would suggest… Continue Reading →

Uncheck the box to turn MathJax off. This feature requires Javascript. Click on a formula to zoom. Abstract p-Values are viewed by many as the root cause of the so-called replication crisis, which is characterized by the prevalence of positive scientific findings that are contradicted in subsequent studies. The spectrum of proposed solutions includes redefining statistical significance, abandoning the concept of statistical significance, or eliminating the use of p-values altogether. The unintended consequence of these proposals has been confusion within the scientific community, especially in the absence of consensus or clear alternatives. The goal of this… Continue Reading →
