Calculate sampling error with our simple Margin of Error calculator. Find out how much the opinions and behavior of the sample you survey is likely to deviate from the total population.
We use the equation to examine the effect of sample size, response rates and sample variability on the estimated sampling margin of error, and present results in four tables that allow users to assess the interpretative validity (IV) of a SET score for a specific evaluation context. In this ...
