Finite Population Sample Size Formula. Aug 25 2012 Sample Size Formula for Finite Population. This is because a given sample size provides proportionately more information for a small population than for a large population.
Where n is the sample size and N is the population size. In that case the formula to calculate sample size is. For a confidence level of 95 α is 005 and the critical value is 196 MOE is the margin of error p is the sample proportion and N is the population size.
N NX X N 1 where X Z α22 p 1-p MOE 2 and Z α2 is the critical value of the Normal distribution at α2 eg.
Finite and Infinite Population A scenario where the sample size n is MORE THAN 5 OF THE POPULATION SIZE N is called a FINITE POPULATION. If Finite Population Sample Size for Finite Population Samplesize 1 Samplesize - 1Population Confidence Interval m sqrt Z2 p 1 -. Where subscript Y Yamane. SS Z 2 p 1 p C 2.
