The standard error is an estimate of the standard deviation of a statistic. This lesson shows how to compute the standard error, based on sample data.
One can find the standard deviation of an entire population in cases (such as standardized testing) where every member of a population is sampled.

Sample Error Calculators | Health Care Research Calculators – DSS provides online calculators to address issues of sample size for samples involving the estimation of proportions.
Assume the population standard deviation is 6. Use the TI-83 calculator to test the hypothesis that the population mean is not different. The sample proportion is 30% or p = 0.30, and the hypotheses are H0: p ≥ 0.35 and H1: p < 0.35 (claim).
