As for categorical variables, the chi-square test (χ2) willbe used for continuous variables, Variance Analysis, when unidirectional analysis of variance (Unidirectional ANOVA) is detected. The effect size will be calculated using Cramer's V test (nominal variables) and the eta-square test (continuous variables
