| A survey of this size can have a sampling error of plus or minus 3 percentage points, and there are other possible sources of errors in all polls. The sampling error on the total sample is plus or minus two percentage points at the 95% confidence level. In a well-designed statistical sample, the sampling error is as small as we need it to be. |
