Use the power explorers to calculate sample size for hypothesis tests. Explore the impact of sample size on the power of a hypothesis test to detect a specified difference where the difference could be from a constant (one-sample case) or between two groups (two-sample case). For the one-sample case, the hypothesis is about the single parameter (mean, proportion, or variance). For the two-sample case, the hypothesis is about comparing two groups. For more than two groups, you can use the Power Explorer for ANOVA, see Power for ANOVA.

For hypothesis testing, select DOE > Sample Size Explorers > Power:

• Power for One Sample Proportion

• Power for One Sample Variance

• Power for One Sample Equivalence

• Power for Two Independent Sample Means

• Power for Two Independent Sample Means

• Power for Two Independent Sample Variances
