Web20 apr. 2016 · A test statistic is a standardized value that is calculated from sample data during a hypothesis test. The procedure that calculates the test statistic compares your data to what is expected under the null hypothesis. Each type of t-test uses a specific procedure to boil all of your sample data down to one value, the t-value.
WebCritical values for a test of hypothesis depend upon a test statistic, which is specific to the type of test, and the significance level, α, which defines the sensitivity of the test.
