(e.g., 69% ± 3.8%) critica. 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.
Hypothesis Testing Cheat Sheet Qlmacros Download Printable Pdf Master statistics with our hypothesis testing cheat sheet. learn how to choose tests, interpret p values, and avoid errors with this quick reference guide. This cheat sheet outlines key concepts and steps in hypothesis testing, including definitions of significance level, confidence level, critical value, test statistic, p value, null hypothesis, and alternative hypothesis. Hypothesis testing cheat sheet e.g. when comparing two samples a 2 sample t test shows = 0.128 where α = 0.05. We decide first what probability (i.e. risk that we reject the hypothesis even though it is correct) we find acceptable (e.g. 1%, 5% or 10%) and we then work out the relevant c. those risk levels are also referred to as significance levels.

Define h0 (null hypothesis) and ha (alternative hypothesis). select a significance level α such as 0.05. collect sample data from the population. calculate the test statistic using the sample data. determine the p value or critical value. compare the p value with α. reject h0 or fail to reject h0.
