All of the options can increase power. A greater difference produced by the independent variable will increase the effect size, making it easier to detect a significant difference between conditions. Smaller variability in raw scores will decrease the error variance, making it less likely that a significant difference between conditions is due to chance. Increased sample size provides more power to detect significant differences, allowing for a better chance to detect a true effect.
