What Is Not Required To Determine Minimum Sample Size. Take the example discussed above where the the minimum sample size is computed to be N 9. In order to determine the sample size needed the investigator must specify the desired margin of error.
If your population is less than 100 then you really need to survey all of them. Often times we are interested in estimating a population parameter like the population mean mu within a certain range of precision. Our calculator shows you the amount of respondents you need to get statistically significant results for a specific population.
This estimate is low.
Dummies helps everyone be more knowledgeable and confident in applying what they know. Take the example discussed above where the the minimum sample size is computed to be N 9. You should also use this percentage if you want to determine a general level of accuracy for a sample you already have. Determine the minimum sample size required when you want to be 90 confident that the sample mean is within one unit of the population mean and sigmaequals173.
