Question

Quizplus · Accepted Answer

ANOVA (analysis of variance) is the most appropriate test of significance when dealing with an interval-ratio dependent variable and an independent variable with three or more categories. The t-test is only appropriate when there are two categories for the independent variable, and Chi square is more appropriate for nominal or ordinal data. The IQV is not a commonly used statistical test in research.
