## tandfonline.com – Why is Getting Rid of P-Values So Hard? Musings on Science and Statistics

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT The current concerns about reproducibility have focused attention on proper use of statistics across the sciences. This gives statisticians an extraordinary opportunity to change what are widely regarded as statistical practices detrimental to the cause of good science. However, how that should be done is enormously complex, made more difficult by the balkanization of research methods and statistical traditions across scientific subdisciplines. Working within those sciences while also allying with science reform movements—operating simultaneously on the micro and macro levels—are the key to making lasting change in applied science.

## tandfonline.com – Valid P-Values Behave Exactly as They Should: Some Misleading Criticisms of P-Values and Their Resolution With S-Values

Abstract The present note explores sources of misplaced criticisms of P-values, such as conflicting definitions of “significance levels” and “P-values” in authoritative sources, and the consequent misinterpretation of P-values as error probabilities. It then discusses several properties of P-values that have been presented as fatal flaws: That P-values exhibit extreme variation across samples (and thus are “unreliable”), confound effect size with sample size, are sensitive to sample size, and depend on investigator sampling intentions. These properties are often criticized… Continue Reading

## tandfonline.com – The False Positive Risk: A Proposal Concerning What to Do About p-Values

Uncheck the box to turn MathJax off. This feature requires Javascript. Click on a formula to zoom. Abstract It is widely acknowledged that the biomedical literature suffers from a surfeit of false positive results. Part of the reason for this is the persistence of the myth that observation of p < 0.05 is sufficient justification to claim that you have made a discovery. It is hopeless to expect users to change their reliance on p-values unless they are offered an alternative way of judging the reliability of their conclusions. If the alternative method is to have a chance… Continue Reading

## tandfonline.com – Correcting Corrupt Research: Recommendations for the Profession to Stop Misuse of p-Values

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT p-Values and Null Hypothesis Significance Testing (NHST), combined with a large number of institutional factors, jointly define the Generally Accepted Soft Social Science Publishing Process (GASSSPP) that is now dominant in the social sciences and is increasingly used elsewhere. The case against NHST and the GASSSPP has been abundantly articulated over past decades, and yet it continues to spread, supported by a large number of self-reinforcing institutional processes. In this article, the author presents a number of steps that may be taken to counter the spread of this corruption that directly address the institutional forces, both as individuals and through collaborative efforts. While individual efforts are indispensable to this undertaking, the author argues that these alone cannot succeed… Continue Reading

## tandfonline.com – The Role of p-Values in Judging the Strength of Evidence and Realistic Replication Expectations

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
