Sample Size Sample size determination is the act of choosing the number of observations or replicates to include in a statistical sample. The BIGGER the sample size, the better the chance it will give ACCURATE results. Margin of Error Confidence interval, tells you how reliable your surveys are. The higher MOE, the more inaccurate the results are. The lower MOE, the more accurate the results are. A good rule is that if the difference between two numbers or percentages is smaller than the ...
