ANOVA should be used when comparing means across more than two groups. It should be used when working with interval/ratio dependent variables and categorical independent variables. ANOVA demonstrates whether the differences between means across categories of the independent variable are statistically significant.

An experiment with a small sample is conducted to test the effectiveness of a promising new intervention for treating substance abuse. The experimental group's outcome is better than the control group's outcome, but the results are not statistically significant. The implication of this finding for evidence-based practice is:
a. The new intervention was ineffective. b. The new intervention was effective, but not as effective as predicted. c. It is conceivable that the new intervention is effective, although we cannot rule out sampling error as the explanation for the research finding. Additional testing of this intervention with a larger sample size would be in order. d. None of these.
