WebFeb 26, 2010 · Margin of error – the plus or minus 3 percentage points in the above example – decreases as the sample size increases, but only to a point. A very small sample, such as 50 respondents, has about a 14 percent margin of error while a sample of 1,000 has a margin of error of 3 percent.
WebApr 2, 2024 · When estimating a population mean, the margin of error is called the error bound for a population mean ( EBM ). A confidence interval has the general form: (lower bound, upper bound) = (point estimate– EBM, point estimate + EBM) The calculation of EBM depends on the size of the sample and the level of confidence desired. WebJul 9, 2024 · The number of standard errors you have to add or subtract to get the margin of error, or MOE, depends on how confident you want to be in your results (this is called your confidence level). Typically, you want to be about 95 percent confident, so the basic rule is to add or subtract about 2 standard errors (1.96, to be exact) to get the MOE ...
