Factors Affecting Power in the t TestAfter completing this unit’s assigned readings, discuss one of the following questions: A researcher can do several things to try to increase the magnitude of the effect size d. What are these? Suppose that you can increase the effect size d while holding group sizes n 1 and n 2 constant. How will an increase in effect size d influence the magnitude of t? Several factors influence statistical power for a one-sample t test. How does statistical power change (increase or decrease) for each of the following changes? When d (effect size) increases. When N (sample size) increases. When the alpha level is made smaller. Explain your answer. For example, if we know ahead of time that the effect size d is very small, what does this tell us about the N we will need in order to have adequate statistical power? (We assume that all other terms included in the r ratio remain the same.)
