How To Graph A Paired T Test - What is a t test? A t test is a statistical technique used to quantify the difference between the mean (average value) of a variable from up to two samples (datasets). The variable must be numeric. Some examples are height, gross income, and amount of weight lost on a particular diet. 1 From the data table click on the toolbar 2 Choose t tests from the list of column analyses 3 On the first Experimental Design tab of t test dialog make these choices Experimental design Paired Assume Gaussian distribution Yes Choose test Paired t test 4 On the options tab make these choices Choose a one or two sided P value

A paired samples t-test is used to compare the means of two samples when each observation in one sample can be paired with an observation in the other sample. This tutorial explains the following: The motivation for performing a paired samples t-test. The formula to perform a paired samples t-test.

How To Graph A Paired T TestWhat is a Paired T Test? Use a paired t-test when each subject has a pair of measurements, such as a before and after score. A paired t-test determines whether the mean change for these pairs is significantly different from zero. This test is an inferential statistics procedure because it uses samples to draw conclusions about populations. 21 It is worth being clear on the purpose of your plot In general there are two different kinds of goals you can make plots for yourself to assess the assumptions you are making and guide the data analysis process or you can make plots to communicate a result to others

The paired t test assumes that you have sampled your pairs of values from a population of pairs where the difference between pairs follows a Gaussian distribution. While this assumption is not too important with large samples, it is important with small sample sizes. Test this assumption with Prism.
