Video shows how to derive the sample size equation from the confidence interval. Video shows how to derive the sample size equation from the confidence interval. A major contribution of biostatistics to biomedical research is in the design of studies that can achieve scientific goals (e.g., .

Known confidence interval and width (unknown population standard deviation) .

The derivations are simplest when one variance is fixed and the second . Where does the sample size equation come from? Formula to determine sample size of population · n = population size, · z = critical value of the normal distribution at the required confidence level, · p = . The values of p1 and p2 that maximize the sample size are p1=p2=0.5.
