# 3 ways to calculate your margin of error when using a sample size calculator!

Calculating margin of error is key to being able to determine the effectiveness and productivity of your survey. Find out the three pieces of data that are necessary to calculate your margin of error!

## 3 ways to calculate your margin of error

When it comes to calculating your sample size and how you can come up with the most accurate survey, you need to know the best way to calculate your margin of error. If you use a sample size calculator, the margin of error can be conducted using a few methods. After all, coming up with an accurate sample size and the margin of error is crucial to putting together a statistically foolproof survey that reflects your target market and your ideal population!

First off – what is the margin of error? Before we can establish how to calculate this analytical stat, we need to know what it means. Simply put, the margin of error is a measure of the percentage your results will stray from the “real” value. If you find that you have a 3 percentage point margin of error from the actual results, you may see that you are within 3 percentage points of the real population value at your calculated confidence level. If you obtain a 97% confidence level and 3 points of margin of error, you will be within 3 points of percentage correct 97% of the time conducting this survey.

Even though it sounds complicated, it just means you have a buffer of 3% accuracy when you are conducting this survey. You can also think of the margin of error as the values that either fall below or above your confidence level when it comes to your survey. In basic terms, the margin of error is the level of uncertainty that you may have about the results – either 3% higher or lower than the real population value.

But how can you calculate your margin of error? You need the basic steps of how to find the critical value, the standard deviation or the standard error, and the correct sample size for the survey. You can find the correct size of how to conduct your survey in the desired population by using a sample size calculator.

• Determine the critical value – you can usually find out the critical value of your margin of error by analyzing the distribution of the test and how it comes to the test statistic.
• Figure out the standard deviation – the next step of using the sample size calculator to determine your margin of error is analyzing the standard deviation. Standard deviation is basically the measure of the spread of numbers that you are using in your survey – you can determine the standard deviation, the standard error by taking the square root of the variance of your data.
• Calculate the sample size – the last step of coming up with your margin of error is to determine your sample size by using the sample size calculator. You can do this by determining the number of people that you should conduct research on in a very large population.

## Conclusion

When it comes to calculating your margin of error, you need to make sure that you take three pieces of data into account – the standard deviation, sample size of your survey, and the critical value. By using a sample size calculator to help you analyze the margin of error, you can come up with a foolproof and reputable survey.
