Two Sample Means Calculator
Use the Two Sample Means calculator to evaluate sample size for a hypothesis test about two means. Explore questions such as how large a treatment effect is detectable for a given sample size, significance level, desired power, and assumed variability in the data. Sample size and power are associated with the following hypothesis test:
versus the two-sided alternative:
where
μ
1
and
μ
2
are the true means of the two populations. It is assumed that the populations of interest are normally distributed and that you want to detect a difference of
δ
between the means.
