In your ongoing quest to develop the best experiment, you decide to use a correlated-groups
design because this helps reduce error variability.
Your colleague, however, recommends using
an independent groups design because these use more degrees of freedom. Which design will
most likely give you the largest test statistic, thereby making it easier to find a significant
difference?
A) independent, because more degrees of freedom increases the test statistic more than it's
reduced by lowering error variability
B) correlated, because the reducing error variability increases the test statistic more than it's
reduced by the fewer degrees of freedom
C) Both approaches will provide the same benefits.
D) Neither, because the test statistic is not affected by degrees of freedom or error variability.
