Misinterpretation of 'p' (1995) (2e)

Authors: Jose D Perezgonzalez [ed]

Falk and Greenbaum (1995) carried out a study on common misinterpretations of the logic of tests of significance among Israeli psychology students, which partly replicates one by Oakes (1986). Typically, most of these misinterpretations confuse p-values (ie, the probability of the data when assuming that the null hypothesis is true) and, especially, statistical significance, with the probability of proving or disproving hypotheses (be this the null hypothesis or an alternative hypothesis). Falk and Greenbaum found that almost 87% of the students held at least one misinterpretation out of the four presented. Most of the students misinterpreted p-values as the probability of the null hypothesis being true.
