| Why should an experiment have high statistical power? | to prevent type II errors |
| Correlation Between IV Levels | only affects power in w/in subject designs; higher correlation between the IV levels gives more power |
| Alpha Level | larger alpha level gives more power |
| Variability in the DV | lower variability gives more power |
| Effect Size | the magnitude of the effect the IV has on the DV; larger effect size gives more power |
| Sample Size | larger sample size gives more power |
