Theoretical error

Definition:

An estimate of the difference between survey results on a specific variable and the long-run mean of that variable if the entire population were measured. The typical standard in research is a 95% confidence level, where in 95 of 100 samples we are sure the true mean falls within the stated range. For instance, suppose a stated 95% confidence interval from a sample of 200 is plus or minus 6.9%. This means that if we repeatedly draw samples of 200 from the given "universe," on 95 out of 100 occasions, we would not expect results to vary by more than plus or minus 6.9 percentage points from the results shown.
