What is the right sample size for a survey?

For most purposes, though, the 1/√N approach is sufficient.) You can quickly see from the table that results from a survey with only 10 random participants are not reliable. The margin of error in this case is roughly 32%.

What is the formula of sample size?

n = N*X / (X + N – 1), where, X = Zα/22 *p*(1-p) / MOE2, and Zα/2 is the critical value of the Normal distribution at α/2 (e.g. for a confidence level of 95%, α is 0.05 and the critical value is 1.96), MOE is the margin of error, p is the sample proportion, and N is the population size.

Is 100 a good sample size?

The minimum sample size is 100 Most statisticians agree that the minimum sample size to get any kind of meaningful result is 100. If your population is less than 100 then you really need to survey all of them.

What is the advantage of the sample size formula?

Larger sample sizes provide more accurate mean values, identify outliers that could skew the data in a smaller sample and provide a smaller margin of error.
