Quizplus · Accepted Answer

A power curve plots the power of a statistical test against different values of the population parameter (e.g., the mean) that make the null hypothesis ($\mathrm { H } _ { 0 }$) false. The power of a test is the probability that the test correctly rejects a false null hypothesis.
