A test statistic is a statistic used in statistical hypothesis testing.

A hypothesis test is typically specified in terms of a test statistic, considered as a numerical summary of a data-set that reduces the data to one value that can be used to perform the 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.

The general formula to find the test statistic is,
