# STANDARD DEVIATION CALCULATOR

## About our standard deviation calculator

Standard deviation calculator provided at the end of this web page will give you the standard deviation of the observations you enter with comma separated. It does not give just only the standard deviation of the given observations and also it gives you mean, population standard deviation, variance, and population variance.As soon as you enter the observations in the box and number of inputs in the box provided,  click the button "calculate", it will give you standard deviation, mean, population standard deviation, variance, and population variance.

## Why do people need this calculator?

Apart from the regular calculator, people who study statistics are in need of this standard deviation calculator. Because, when people work out lengthy problems, they may not have time to  find the standard deviation for the given observations. At that time, calculating  standard deviation would be an additional burden for them in solving lengthy math problems. To reduce the burden of those people, we have provided this online  calculator here.

## Using the calculator in solving word problems

When people do preparation of solving word problems on dispersion, they may have to spend time to get idea on "How to solve". In this situation, they would not like to spend time to find standard  deviation or something like that. Because, when people do word problems on dispersion, they have to do this work separately and they might do some careless mistakes in finding standard deviation. It will definitely disturb the solving of lengthy problem.  And also they would not be able to use the regular calculators to find standard deviation. By using this online calculator, students will find much time to get idea of solving the word problems.

## Advantages of using this online calculator

School students have the topic "Measures of dispersion" in both school level and college level statistics. They are given some observations for which they have to find standard deviation. They find standard deviation as directed in the question.But they are not sure whether the answer they got is correct or incorrect. At that time, they can check the answer they have received is correct or incorrect using this calculator.  .

Apart from the advantages explained above, this calculator can also be used to find mean, population standard deviation, variance and population variance.
