Question

Quizplus · Accepted Answer

Analysis of variance (ANOVA) is the appropriate statistical test when analyzing data with multiple groups, particularly when investigating the interaction effects between two or more independent variables (e.g. dosage level and time of day). T-tests and standard scores are generally used when comparing two groups, while correlation is used to measure the relationship between two continuous variables.
