Step 1. Figure out what you want your confidence level to be. For example,
you might want a confidence level of 95 percent (which will give you
a margin of error of 0.05).
Step 2. Plug your data into the formula. In this example, we’ll use a 95
percent confidence level with a population size of 1,000.
n = N / (1 + N e2)
= 1,000 / (1 + 1000 * 0.05 2)
= 285.714286
Step 3. Round your answer to a whole number (because you can’t sample a
fraction of a person or thing!) 285.714286 = 286
