Factors Affecting Power in the t Test After completing this week's assigned readings, discuss one of the following questions: What things can a researcher do to try to increase the magnitude of the d effect size? Suppose that you can increase the d effect size while holding group sizes n1 and n2 constant. How will an increase in d influence the magnitude of t ? Several factors influence statistical power for a one-sample t test. How does statistical power change...

Dana uses the following parameters to determine that she needs a sample size of 140 participants for her study that will compare the means of two independent groups (t-test) using a one-tailed hypothesis: Effect size (d) = .5 = .05 Power(1 - b) = .90 Using the above information, answer each of the following questions. If Dana keeps alpha and sample size the same, but desires an effect size of .80, what will happen to power? Will it increase or...
