ANOVA (Analysis of Variance) is the appropriate test of significance for research situations in which we have an interval-ratio dependent variable and an independent variable with three or more categories. ANOVA tests whether the means of the groups are statistically different from each other. The t test is used for comparing the means of two groups, while Chi-square is used for comparing categorical variables. IQV is not a known statistical test.
