It is the probability of a positive statistical test results that is actually a type II error - i.e. rejecting the null hypothesis when it is actually correct. For example, if you testing whether A=B; and the test result gives a score that has a p<0.001, it means that the test result suggest that you can be 99.9% sure that A is not equal to B.
