Slovin’s Formula Sampling Techniques * By Steph Ellen‚ eHow Contributor * When it is not possible to study an entire population (such as the population of the United States)‚ a smaller sample is taken using a random sampling technique. Slovin’s formula allows a researcher to sample the population with a desired degree of accuracy. It gives the researcher an idea of how large his sample size needs to be to ensure a reasonable accuracy of results. * When to Use Slovin’s Formula * If
