Determine Minimum Sample Size. Squaring that will make a sample size about 118 times larger and n should be at least 14 or maybe 15. You can calculate the sample size in five simple steps.
Using the sample size formula you calculate the sample size you need is which you round up to 211 students you always round up when calculating n. Thus 186 sample size arrived at should be corrected adjusted for finite population. So you need to take a random sample of at least 211 college students in order to have a margin of.
Sigma σ is provided and the significance level is specified we can compute the minimum required sample size that will lead to a margin of error less than or equal to the one specified by using the following formula.
The significance level represents how sure you want to be that your results are not due to. Choose the required confidence level from the dropdown menu Input the margin of error. In 2001 a Gallup poll surveyed 1016 households in the US about their pets. 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 o 126.
