Abstract: The p-value has been ubiquitous in science for many decades and has been the subject of controversy equally long. The p-value is frequently presented as a measure of evidence on the basis that it is the probability, under the null hypothesis, of observing a value of a relevant summary statistic equal to or more extreme than that actually observed. It is then inferred that a small p-value corresponds to an incompatibility between the data and the null hypothesis. We present an example, in the context of equivalence testing, that demonstrates such logic to be false. Unlike other such examples, the incompatibility of the p-value with this evidential interpretation is demonstrated without reference to external information such as a prior distribution.



Biography: Gary graduated with a PhD in Statistics from Flinders University in 1988. He has held positions at The University of Chicago, Flinders University and The University of Adelaide, where he is presently the Head of the School of Mathematical Sciences.
