The chi-square test is used to determine whether there is a statistically significant association between two or more categorical variables. For instance, educational researchers may want to determine whether the proportions of students preferring online instruction and face to face instruction differ significantly across undergraduate and graduate students. This procedure allows researchers to compare categorical variables across more than two groups and uses the chi-square statistic to determine statistical significance. The following narrated presentation describes the properties of the chi-square distribution and explains how to conduct and interpret the results of chi-square tests. The software tutorial demonstrates how to conduct this procedure in SPSS.
