title: Controlling for Multiple Tests.
abstract: In a statistical test, the P-value is the likelihood that the observed results are just due to chance, and by convention a P-value of <0.05 is considered significant. However, this means that if a study performs 20 individual statistical analyses, assuming the null hypothesis is true in all of them, we expect one to fall below the P<0.05 threshold and give us a false positive. Advanced statistical tests should be used to prevent this from occurring.
