Question

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.)
