Chi-square (χ²) is a statistical test used to determine if there is a significant difference between observed frequencies and expected frequencies in one or more categories. It is not a measure of effect size, unlike Cohen's d, eta squared, and omega squared, which are used to quantify the size of an effect or the strength of a relationship between variables.
