Abstract

We give an example to demonstrate that a conditional statistical test can give a possibly different p-value to an unconditional test, thereby altering the statistical conclusion. This same example also gives different p-values for the associated permutation test and parametric bootstrap test. When there is a choice, whether a test is conditional or unconditional may be important.
