What is a Margin of Error A margin of error tells you how many percentage points your results will differ from the real population value For example a 95 confidence interval with a 4 percent margin of error means that your statistic will be within 4 percentage points of the real population value 95 of the time

The formula is ME(margin of Error)= 2 times the square root of P "hat" times (1 minus P "hat") divide by the amount of people surveyed. The 2 stands for two standard deviation over that stands for 95 % confidence interval. P hat is the result of the survey as a decimal.
