You can use a paired test when there is a natural pairing of observations in the samples, such as when a sample group is tested twice - before and after an experiment. This t-test form does not assume that the variances of both populations are equal. T-Test: Paired Two Sample For Means This analysis tool and its formula perform a paired two-sample student's t-test to determine whether a sample's means are distinct.

Because the result of the calculation is usually not an integer, use the nearest integer to obtain a critical value from the t table. The following formula is used to approximate the degrees of freedom. The following formula is used to determine the statistic value t. Use a paired test when there is one group before and after a treatment.

Use this test when the groups under study are distinct. You can use a t-test to determine whether two sample means are equal. This t-test form assumes that the variances of both ranges of data are unequal it is referred to as a heteroscedastic t-test. T-Test: Two-Sample Assuming Unequal Variances This analysis tool performs a two-sample student's t-test. You can use t-tests to determine whether two sample means are equal. This t-test form assumes that the means of both data sets are equal it is referred to as a homoscedastic t-test. T-Test: Two-Sample Assuming Equal Variances This analysis tool performs a two-sample student's t-test.

The t-Test analysis tools test the means of different types of populations.
