# Sample Size Calculation and Statistical Analysis

### (4/06/2011)

We give some examples of power analysis/sample size
paragraphs that can be adapted and specialized for your proposals. These
examples have actually been used and considered adequate in proposals. However
please remember that reviewers differ considerably in their views of what constitutes
an acceptable power analysis; e.g., some require sample size/power computations
for each hypothesis or minimum effect size hypotheses. We recommend giving as
much detail as is possible within the current page limitations for proposals,
and whenever possible linking effect sizes to metrics reflecting potential
clinical outcomes.
