WebGenerally, the test statistic is calculated as the pattern in your data (i.e. the correlation between variables or difference between groups) divided by the variance in the data (i.e. the standard deviation ). Frequently asked questions: Statistics What happens to the shape of Student’s t distribution as the degrees of freedom increase? WebThe steps to perform a test of proportion using the critical value approval are as follows: State the null hypothesis H0 and the alternative hypothesis HA. Calculate the test statistic: z = p ^ − p 0 p 0 ( 1 − p 0) n. where p 0 is the null hypothesized proportion i.e., when H 0: p = p 0. Determine the critical region. Make a decision.
