Question

Quizplus · Accepted Answer

Power increases with increasing N (sample size), increasing magnitude of the effect of the independent variable, increasing a level (alpha level) and the magnitude of the difference between µ real (true population mean) and µ null (hypothesized population mean). Therefore, all of these factors contribute to an increase in statistical power.
