Sampling Frame Error Definition
The most conservative number for this proportion is .50 and if the desired accuracy was .05 and the formula would appear as: (Number of Standard Errors)2 * ((proportion)*(1-proportion)) / (Accuracy) ---------------------------------------------------------------------------- It is most commonly used in testing hypotheses, especially for small samples.
