Figure 13.1 presents the variable view of the SPSS data editor where we have. Notice that many of the statistics are 2-tailed tests. types of nonparametric chi-squares: The Goodness-of-Fit chi-square and. We would be more inclined to use Fisher’s Exact Test, if instead we could not meet the assumption of 5 observations per cell. Generally, when looking at these chi-square tests, we’re interested in Pearson’s Chi-Square value. We do so simply by looking at the relative counts for each category. So, click on Grouping 1 and Grouping 2, and then click on the highlighted arrow. You’ll want to include both your grouping variables in the Test Variable List. If it worked, the following window should have appeared.
While this does not tell us the direction, from the table above we could readily infer which direction the frequencies (might be) skewed. Like most analyses in SPSS, we are going to start by clicking the Analyze tab at the top,then Legacy Dialogs, and then Chi-square. The test here indicates that there is no significant effect, p =. In the above output, we get a table that tells us the frequency for each category and a table with testing information. The output for the Chi-square test should be given below: It does not matter whether the IV or the DV go into a particular box. The chi-square test of independence uses to investigate the relationship between two categorical variables that have two or more categories.

Move the two variables you wish to test for a relationship between into the boxes labeled rows and columns. This easy tutorial will show you how to run the Chi-Square test in SPSS, and how to interpret the result. On the main toolbar click Analyze –> Descriptive Statistics –> Cross-tabs Because each of these groups have data recorded as a binary (0/1 for male/female and 0/1 for minority/non-minority), we would want to use a chi-square to analyze these categories. Suppose we were interested in investigating whether there was a significant difference in the number of male or female minority students in the data set maybe we have reason to think that there are more female minority students in the data file than male minority students.

To demonstrate the analysis, we’ll be using the HSB data file, which is free to download.
Generally, it’s not a big deal if this assumption is violated, because we are given other statistical tests in the output that correct for this possibility.
The expected frequency of each category must be 5 or more. The data are obtained from a random sample.Ģ. Basically, we’re going to compute a cross-tabulation to ask if there’s a greater frequency of some kind of outcome event in group A compared to group B. A chi square analysis is used when we have a categorical dependent and independent variable.
