Sample Size Calculator Two Independent Groups. A parallel designed clinical trial compares the results of a treatment on two separate groups of patients. For a confidence level of 95%, α is 0.05 and the critical value is 1.96), z β is the critical value of the normal distribution at β (e.g.

The sampled individuals) in the two groups are independent.

Two study groups will each receive different treatments. Comparing two independent samples (to use this page, your browser must recognize javascript.) choose which calculation you desire, enter the relevant population values for mu1 (mean of population 1), mu2 (mean of population 2), and sigma (common standard deviation) and, if calculating power, a sample size (assumed the same for each sample). The sample size calculated for a parallel design can be used for any study where two groups are being compared. For a power of 80%, β is 0.2 and the critical value is 0.84) and p 1 and p 2 are the expected sample proportions of the two groups.
