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

required by the study Determine sample size ▪ Slovin Formula: ▪ n = N__ ▪ 1+NE² ▪ Where: n = sample size ▪ N = population size E = margin of error * desired Example: What should be the representative sample size if the population from which the sample will be taken is 10‚000 and the desired margin of error is 2%? Solution: To determine the sample size‚ use the formula; n = ___N__ 1+NE² n =

acceleration due to gravity at the Earth’s surface (g) g’ = (re2 / r2) g Acceleration due to gravity inside the Earth Here let r represent the radius of the point inside the earth. The formula for finding out the acceleration due to gravity at this point becomes: g’ = ( r / re )g In both the above formulas‚ as expected‚ g’ becomes equal to g when r = re.
