This will place Class in the other window, as seen below: Click on Class, then click on the highlighted arrow. We are going to recode the Class variable. You should then have a window that looks like the one below: To start this process, click on Transform and then Recode into Difference Variables. Fortunately, creating a dummy variable is fairly easy. Smith’s class, which is called a dummy-coded variable. Howard’s class and 1s for everyone in Dr. So, we need to create a new variable with 0s for everyone in Dr. In SPSS, a two-sample t-test must be performed with a grouping variable that contains numerical values or very short text. We first need to make a new grouping variable, because our current grouping variable in our dataset (Class) consists of fairly long text. It may be difficult to follow along if your dataset looks differently. If it doesn’t, you may need to reformat your dataset. The data should look something like this: Smith) to determine which class has higher grades on an exam. In the example dataset, we are comparing the test grades of two classes (Dr.

If you don’t have a dataset, download the example dataset here. Now that we know what a two-sample t-test is used for, we can now calculate a two-sample t-test in SPSS! To begin, open your data in SPSS.

Instead, I prefer to say that a two-sample t-test is used to “test whether the means of a measured variable in two groups is significantly different.” So, a two-sample t-test is used to answer questions that are similar to the following: The textbook definition says that a two-sample t-test is used to “determine whether two sets of data are significantly different from each other” however, I am not a fan of this definition. As always, if you have any questions, please email me a learning about two-sample t-tests in SPSS, we must first know what a two-sample t-test is used for. For this reason, I created the page below to provide an easy-to-read guide on performing two-sample t-tests in SPSS. Because the students are still getting used to functions in SPSS, they tend to have many difficulties with this lesson. I often use two-sample t-tests as an introduction to SPSS in my undergraduate statistics courses – and sometimes my graduate courses, too.
