At a 90-10 division of opinion, rather than 50-50, still at 95 percent confidence, sampling error for 1,000 interviews is +/- 2 points, not 3. For a sample of 100 cases ā€“ roughly the minimum sample size ABC News will report ā€“ the error margin is +/- 10 points at a 50-50 percent division, +/- 8.5 points at 75-25 percent and +/- 6 points at 90-10 percent. (ABC News polls at times will oversample small populations to increase their sample size to a level we consider reliably reportable.) Show how they are getting these ā€œmargin of sampling errorsā€ above, using specific values in the relevant formula to show you get the margin of error percentages listed.
