A test statistic is a standardized value that is calculated from sample data during a hypothesis test. You can use test statistics to determine whether to reject the null hypothesis. The test statistic compares your data with what is expected under the null hypothesis.
1 State the null and research hypotheses. 2  Establish the level of statistical significance (alpha level, level of risk for committing a Type I error). 3  Select the appropriate test statistic (see the decision tree on page 166 or https://usffiles.usfca.edu/FacStaff/baab/www/lessons/DecisionTree.html). The appropriate test to use is a t test. 2  The test statistic will be t. 3  Check the test's assumptions and the compute the test statistic based on the sample data (obtained value). 4  The assumption of independence is met because we are comparing different schools.
