How to Interpret Margin of Error (With Examples)
WebApr 25, 2024 · Confidence Interval = [lower bound, upper bound] The margin of error is equal to half the width of the entire confidence interval. For example, suppose we have the following confidence interval for a population proportion: 95% confidence interval = [0.34, 0.46] The width of the confidence interval is 0.46 – 0.34 = 0.12.
