Slovin's formula allows a researcher to sample the population with a desired degree of accuracy slovin's formula gives the researcher an idea of how large the sample size needs to be to ensure a reasonable accuracy of results. 1 slovin sample size calculator for limited prior information using below formula: 2 sample size calculator for categorical data a) infinite population using below formula: b) finite population 3 sample size calculator population for numerical data a) infinite population using below formula: b) finite population. View our sample size formulas for our sample size calculator from creative research systems. Using slovin's formula, you would be required to survey n = n / (1 + ne^2) people: 1,000 / (1 + 1000 005 005) = 286 powered by create your own unique website with customizable templates.
Give at least one example of slovin's computation. This is the minimum recommended size of your survey if you create a sample of this many people and get responses from everyone, you're more likely to get a correct answer than you would from a large sample where only a small percentage of the sample responds to your survey.

The formula to find a raw score is x = x_bar + z s x represents the raw score, x_bar is the mean, z is the z-score and s is the standard deviation to determine the raw score, these values must be known the raw score allows students to find their letter grades on curved tests for example, if a. Slovin's formula widely used to calculate minimum sample size from finite population, but the original reference not available, i suppose you can use other reference as cited by ( ) , i hope the. Sample question: use slovin’s formula to find out what sample of a population of 1,000 people you need to take for a survey on their soda preferences step 1: figure out what you want your confidence level to be for example, you might want a confidence level of 95 percent (giving you an alpha level of 005), or you might need better accuracy at the 98 percent confidence level (alpha level.
