description The statistical methods used by the ATLAS Collaboration for setting upper limits or establishing a discovery are reviewed, as they are fundamental ingredients in the search for new phenomena. It is recommended to test different approaches, including at least one frequentist and one Bayesian method. After the introduction of the necessary basic concepts of statistical hypothesis testing, the details of a frequentist approach based on the profile likelihood ratio are provided, and the Bayesian method for dealing with Poisson processes based on Jeffreys' priors is also addressed.
