Statistical significance testing can be viewed as a formal method for assessing the evidence with regard to a scientific conjecture. It reflects the degree to which we can be confident that an association observed in the study sample is also present in the target population. Significance tests play a central role in psychiatric epidemiology, and in fact across the full gamut of human research. Given the omnipresence of statistical significance tests, it is essential for all investigators to understand the principles behind these tests and guidelines for their interpretation. This chapter provides this background and makes recommendations for sensible evaluation of test results.
