How To Find Margin Of Error From Confidence Interval?

Margin of error = (upper confidence limit – lower confidence limit) / 2

Margin of error = upper confidence limit – point estimate

Margin of error = point estimate – lower confidence limit

For a confidence interval written as estimate ± margin of error, the margin of error is the value after ±

Example: if the confidence interval is 12 to 18, margin of error = (18 – 12) / 2 = 3
