Which factor is NOT a limitation of power analysis?Review LaterAssumptions about effect sizeDeviations from statistical assumptionsStudy design and measurement errorThe selection of an appropriate statistical test

Power analysis helps enhance the reliability and validity of research findings by:Review LaterMinimizing the risk of Type I errorsMinimizing the risk of Type II errorsMaximizing the sample sizeMaximizing the effect size

What is the purpose of power analysis?Review LaterTo determine the effect size of a study.To determine the variability of a study.To determine the sample size needed for adequate power.None of the above

What is the purpose of a power analysis in inferential statistics?*1 pointa. To determine the statistical significance of a resultb. To estimate the sample size required to detect an effect of a certain sizec. To calculate the effect size in a studyd. To assess the normality of the data distribution

.Question 18From many prior studies, a researcher expects an effect size of d = .57 for a new study, but a new colleague has suggested that an effect size of d = .42 is more reasonable given the change in the research design. If the effect size does decrease, then how would the expected power of the study change?1 pointPower would decrease.Type I errors would increase.Power would increase.β would decrease.

In hypothesis testing, what is the purpose of conducting a power analysis?  A. To determine the p-value  B. To calculate the effect size  C. To estimate the probability of a Type II Error  D. To define the null hypothesis
