Explain the four factors that determine statistical power.
What will be an ideal response?
There are four factors that determine statistical power:
(1) the effect size to be detected,
(2) the alpha level threshold for statistical significance,
(3) the sample size, and
(4) the statistical significance test used. The effect size to be detected in the context of impact evaluation is the MDES that has been identified to represent the threshold effect size for practical significance, so that is a given as a component of the statistical power function. The alpha level is set by the evaluator, by convention usually .05, and is, thus, also a given.The sample size factor is fairly straightforward—larger samples increase the statistical power to detect an effect. Planning for the best statistical testing approach is not so straightforward. The most important consideration involves the use of baseline covariates in the statistical model applied in the analysis.
