In statistics, there are four kinds of t-test ( t-test ), namely:

1. Test the hypothesis that the mean of the population is equal to a certain value
2. Test the hypothesis for the difference in the mean of two random samples with the same variance ( t-Test: Two-Sample Assuming Equal Variances )
3. Test the hypothesis for the difference in the mean of two random samples with unequal variances ( t-Test: Two-Sample Assuming Unequal Variances )
4. Test the hypothesis for the mean of the sample in paired observations ( t-Test: Paired Two Sample For Means )

The following is a two-way student t-test tutorial to compare two median values of a random sample (population) with the same variance ( t-Test: Two-Sample Assuming Equal Variances ) using the Add-Ins Analysis Toolpak Excel. This t-test assumes that the two data groups come from a distribution with the same variance.
