(video) What is a Margin of Error? The margin of error is the range of values below and above the sample statistic in a confidence interval. The confidence interval is a way to show what the uncertainty is with a certain statistic (i.e. from a poll or survey). For example, a poll might state that there is a 98% confidence interval of 4.88 and 5.26. That means if the poll is repeated using the same techniques, 98% of the time the true population parameter (parameter vs. statistic) will fall within the interval estimates (i.e. 4.88 and 5.26) 98% of the time. What is a Margin of Error Percentage? A 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 populat

By calculating your margin of error (also known as a confidence interval), you can tell how much the opinions and behavior of the sample you survey is https://www.surveymonkey.com/mp/margin-of-error-calculator/ likely to deviate from the total population. This margin of error calculator makes it simple. Calculate Your Margin of Error: The total number of people whose opinion or behavior your sample will represent. Population Size: The probability that your sample accurately reflects the attitudes of your population. The industry standard is 95%. Confidence Level (%): 8085909599 The number of people who took your survey. Sample Size: Margin of Error (%) -- *This margin of error calculator uses a normal distribution (50%) to calculate your optimum margin of error.
