### Chi-Square

Chi-Square is a statistical test that can be used to analyze results from categorical variables. Categorical variables are variables that contain clearly different groups. The chi-square statistic is used with frequency data.  The chi-square value is reported with a probability ( p ) value indicating significance.  For example, we can use chi-square to test for an association between frequency of attendance at organizational meetings and age groups (category variable).  Common measures of effect size associated with chi-square analyses are Cramer’s V or the phi coefficient.
