Several factors influence statistical power for a one-sample t 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.)
