Confidence level affect margin of error
WebA margin of error tells you how many percentage points your results will differ from the real population value. For example, a 95% confidence interval with a 4 percent margin of error means that your statistic will be within 4 percentage points of the real population value 95% of the time. However, there’s a little more to the formal definition. WebConfidence levels are the long-run percentage of times that the population value falls within the MOE.
