How to determine sample size from a given study population?Lazarus Gawazah
In order for your survey to be representative for an entire population, you need to calculate the number of respondents: the survey sample size. Here's how!
Don't let your research project fall short - learn how to choose the optimal sample size and ensure accurate results every time.
For instance, if you have a population of 250,000, 10% would be 25,000. Since this is higher than 1,000, a sample size of 1,000 should be enough to get you statistically significant results. How to Determine Sample Size for a Survey Calculating sample size can be made easier with so...

sample mean. Let's say that you are measuring the wingspan of your duck population from above and you find a mean wingspan of 24 inches. To calculate the standard deviation you will need determine how different each measurement is from the mean, square each of those differences, add them ...
Other places where the range rule is helpful are when we have incomplete information. Formulas such as that to determine sample size require three pieces of information: the desiredmargin of error, thelevel of confidence, and the standard deviation of the population we are investigating. Many time...
