a percentage it is z*·√(p(1 − p) / n), where p is the sample proportion, n the sample size and z* the critical value for your confidence level (1.96 for 95%). The default 50% proportion gives the most conservative (largest) margin, because the quantity p(1 − p) peaks at p = 0.5, which is why pollsters often quote it. To halve that margin, you would need roughly four times the sample. To halve that margin, you would need roughly four times the sample.It reports the margin of error, the confidence-interval bounds around your proportion and the full interval width, and a table shows how it shrinks as the sample grows. To halve that margin, you would need roughly four times the sample.It reports the margin of error, it reports the margin of error.ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:ItWorked example:
