B) An ANOVA
C) A t-test
D) A reliability index

Question

Quizplus · Accepted Answer

An ANOVA (Analysis of Variance) is the most appropriate analysis for comparing the means of three or more groups, such as the three different doses of a drug in this experiment, on a continuous outcome variable like reaction time. The t-test is used for comparing the means of two groups and is not appropriate for this experiment. The Chi-Square is used for analyzing categorical variables and is not applicable in this scenario. A reliability index is used to assess the consistency and accuracy of a measurement tool and is not relevant to this analysis.
