Question

Quizplus · Accepted Answer

The t test or ANOVA are statistically appropriate procedures for testing mean differences between groups or phases. Time series analysis is typically used to assess patterns over time rather than mean differences. Tukey's mean test is a post-hoc test used after an ANOVA to determine which groups or phases are significantly different from each other in terms of their means.
