In our enhanced chi-square test for independence guide, we show you how to correctly enter data in SPSS Statistics to run a chi-square test for independence. In SPSS Statistics, we created two variables so that we could enter our data: Gender and Preferred_Learning_Medium. Therefore, we have two nominal variables: Gender (male/female) and Preferred Learning Medium (online/books). An educator would like to know whether gender (male/female) is associated with the preferred type of learning medium (online vs. However, different people learn in different ways. It explains when you should use this test, how to test assumptions, and a step-by-step guide. With current technology, it is possible to present how-to guides for statistical programs online instead of in a book. How to perform a chi-square test of association using SPSS. SPSS Statistics ExampleĮducators are always looking for novel ways in which to teach statistics to undergraduates as part of a non-statistics degree course (e.g., psychology). First, we introduce the example that is used in this guide. In the section, Procedure, we illustrate the SPSS Statistics procedure to perform a chi-square test for independence. Example independent variables that meet this criterion include gender (2 groups: Males and Females), ethnicity (e.g., 3 groups: Caucasian, African American and Hispanic), physical activity level (e.g., 4 groups: sedentary, low, moderate and high), profession (e.g., 5 groups: surgeon, doctor, nurse, dentist, therapist), and so forth. Assumption #2: Your two variable should consist of two or more categorical, independent groups.You can learn more about ordinal and nominal variables in our article: Types of Variable. Assumption #1: Your two variables should be measured at an ordinal or nominal level (i.e., categorical data). The chi-square statistic is a measure of divergence between your datas distribution and an expected or hypothesized distribution of your choice.If it does not, you cannot use a chi-square test for independence. As part of a study on breeding efficiency in Standardbred mares the following data were collected to investigate the. For example, typing 2 for the Degrees of freedomand 0.38 for the Input constant returns 0.173, which is one minus the upper-tail area for a chi-squared statistic of 0.38 from the chi-squared distribution with 2 degrees of freedom (i.e., the p-value is 10.1730.827). You need to do this because it is only appropriate to use a chi-square test for independence if your data passes these two assumptions.

In the previous activity, we carried out the chi-square test using Minitab and obtained the. When you choose to analyse your data using a chi-square test for independence, you need to make sure that the data you want to analyse "passes" two assumptions. Minitab Instructions: Test of Independence Using Technology. The chi-square test for independence, also called Pearson's chi-square test or the chi-square test of association, is used to discover if there is a relationship between two categorical variables.
