Once you've gathered that information, you can calculate by
hand using a formula found in many textbooks, use one of
many specialized software packages, or hand it over to a
statistician, depending on the complexity of the analysis.
But regardless of which way you or your statistician
calculates it, you need to first do the following 5 steps:
Step 1. Specify a hypothesis test.
Most studies have

with steps many hypotheses, but for sample size
calculations, choose one to three main hypotheses. Make
them explicit in terms of a null and alternative
hypothesis.
Step 2. Specify the significance level of the test.
It is usually alpha = .05, but it doesn't have to be.
Step 3. Specify the smallest effect size that is of
scientific interest.
This is often the hardest step. The point here is not to
specify the effect size that you expect to find or that
others have found, but the smallest effect size of
scientific interest.
