D) Rimsky-Korsakov test

Quizplus · Accepted Answer

Two-factor ANOVA with replication is the most appropriate test since there are two independent factors (age and type of surgery) and the data has been collected from three patients in each category. It allows us to test the main effects of each factor as well as their interaction. One-factor ANOVA is not appropriate because there are two factors involved, and Two-factor ANOVA without replication is not appropriate because there are only three observations per category. Rimsky-Korsakov test is not a statistical test and is not appropriate for this type of data.
