WebIn other words, the margin of error is larger. We know that a higher confidence level gives a larger margin of error, so confidence level is also related to precision. Increasing the confidence in our estimate makes the confidence interval wider and therefore less precise. WebTo calculate a confidence interval, take the critical value (Z or t) and multiply it by the standard error of the mean (SEM). This value is known as the margin of error (MOE). Then add and subtract the MOE from the sample mean (x̄) to …

WebThis implies that the reliability of the estimate is more strongly affected by the size of the sample in that range. In contrast, the margin of error does not substantially decrease at sample sizes above 1500 (since it is already below 3%). WebThis interval is called the confidence interval, and the radius (half the interval) is called the margin of error, corresponding to a 95% confidence level.
