Hypothesis Testing Cheat Sheet 23 June 2022 Hypothesis Terms Definitions Significance Level (𝜶) Defines the strength of evidence in probabilistic terms. Specifically, alpha represents the probability that tests will produce statistically significant results when the null hypothesis is correct. In most fields, α = ì. ì5 is used most often.

Type I Error: Reject the null hypothesis when the null hypothesis is true Type II Error: Do not reject the null hypothesis when the al-ternative hypothesis is true Test Statistics (t): A single number that summarizes the sam-ple data used to conduct the test hypothesis Standard Error: How far sample statistics (e.g., mean) devia-
