a ratio 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. 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. The default 50% margin of error is 1.96 × 0.5 × 0.5 ÷ 1000 ≈ 0.0158.It reports the margin of error.Worked example:Worked example:
