WebThe formula for the test statistic depends on the statistical test being used. Generally, 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 WebIf the p p -value is lower than the significance level we chose, then we reject the null hypothesis H_0 H 0 in favor of the alternative hypothesis H_\text {a} H a. If the p p -value is greater than or equal to the significance level, then we fail to reject the null hypothesis H_0 H 0, but this doesn't mean we accept H_0 H 0. To summarize:
