Psychology journal bans P values

Nature volume 519, page 9 (2015)Cite this article

Subjects

09 March 2015 This story originally asserted that “The closer to zero the P value gets, the greater the chance the null hypothesis is false.” P values do not give the probability that a null hypothesis is false, they give the probability of obtaining data at least as extreme as those observed, if the null hypothesis was true. It is by convention that smaller P values are interpreted as stronger evidence that the null hypothesis is false. The text has been changed to reflect this.

Test for reliability of results ‘too easy to pass’, say editors.
