On the Use and Misuse of Tests of Significance

Peter Guttorp

Seminar

University of Washington - Department of Statistics

There have been several instances recently of papers in the scientific literature insisting that significance tests are misleading. I will first go back to some of the original writing (by Fisher, Jeffreys, Neyman and Pearson) on testing. Then I will discuss the issue of how to set null hypothesis, the logic of tests of significance as part of the scientific method, and the distinction between real correlation and physical relationship.
