Labels:reckoner | sky OCR: The Power The power the probability of getting a significant result It is a function of the sample size n the effect size Ideltal the standard deviation of the erroro, and the significance leveb. The power tells you how likely your experiment detect differences at given alpha level. Power has the following characteristics. the true value of the parameter is the hypoth esized value the powe should be alpha, the size of the test. You do not want to reject the hypothesis when it is true. .|f the true value of the parameters is not the hypothesized value you want the power to be as great as possible The power increases with the sample size The power increases as the error variance decreases. The power increases as the true parameter gets farther from the hypothesized value hvpothesizec
