An Alternative to Null-Hypothesis Significance Tests [PDF]

open access: yesPsychological Science, 2005
The statistic Prep estimates the probability of replicating an effect. It captures traditional publication criteria for signal-to-noise ratio, while avoiding parametric inference and the resulting Bayesian dilemma. In concert with effect size and replication intervals, Prep provides all of the information now used in evaluating research, while ...

Manipulating the Alpha Level Cannot Cure Significance Testing

open access: yesFrontiers in Psychology, 2018
We argue that making accept/reject decisions on scientific hypotheses, including a recent call for changing the canonical alpha level from p = 0.05 to p = 0.005, is deleterious for the finding of new discoveries and the progress of science.

P-Value demystified

open access: yesIndian Dermatology Online Journal, 2019
Biomedical research relies on proving (or disproving) a research hypothesis, and P value becomes a cornerstone of “null hypothesis significance testing.” P value is the maximum probability of getting the observed outcome by chance. For a statistical test

The Fallacy of the Null Hypothesis Significance Test [PDF]

open access: yesPsychological Bulletin, 1960
The theory of probability and statistical inference is various things to various people. To the mathematician, it is an intricate formal calculus, to be explored and developed with little professional concern for any empirical significance that might attach to the terms and propositions involved.

A Review of Bayesian Hypothesis Testing and Its Practical Implementations

open access: yesEntropy, 2022
We discuss hypothesis testing and compare different theories in light of observed or experimental data as fundamental endeavors in the sciences. Issues associated with the p-value approach and null hypothesis significance testing are reviewed, and the ...
