The first group receives no amphetamine, the second group receives 0.5 mg/kg, the third group receives 1.0 mg/kg, and the fourth group receives 2 mg/kg. What initial statistical test should Dr. Symon use to examine the effects of the drug?

C) one-way analysis of variance
D) two-way analysis of variance

Question

Quizplus · Accepted Answer

Dr. Symon should use a one-way analysis of variance (ANOVA) because he is comparing the means of more than two groups (different doses of amphetamine) on a single independent variable (dose) to see if there is a significant effect on the dependent variable (maze running performance).
