Mathematical operators. Excel Toolbox. When choosing a t test, you will need to consider two things: whether the groups being compared come from a single population or two different populations, and whether you want to test the difference in a specific direction Compare Means sub-menu in SPSS), there are three kinds of t-test: the one-sample t-test, the independent-samples t-test, and the paired-samples t-test. Independent (unpaired) t-test. One of the simplest situations for which we might design an experiment is the case of a nominal two-level explanatory variable and a quantitative outcome variable. You will learn how to use the t-test in three different types of hypotheses. In this case, the t distribution is a normal distribution. After making sure the scores in your data file look exactly like those in Image 1, click “Analyze” and then go to “Compare Means” and “One Sample T-Test”.

The one-sample (or univariate) t-test is for when you use a single set of values to test Hμ = V. For example, you want to know if people (in general) can perform a task without simply guessing the sample size as infinite. You can see this in the t table in Appendix C.
