Standard error calculator is an online statistical tool to find out the standard error of a population. It is nothing but the standard deviation of the sampling distribution. The equation of the standard error is given as,


Where $SE_{x}$ is the standard error
          S is the sample standard deviation
          n is the number of observations
Following steps are used to find out the standard error.

Note down the given observations from the question.

Find out the mean of the given data.
$\mu$ =$\frac{x_{1}+x_{2}+.......+x_{n}}{n}$

Step3: Calculate the sample standard deviation using the given formula.
S=$\sqrt{\frac{1}{n-1}\sum_{i=1}^{n}(x_{i}-\mu )^{2}}$

Step3: Using the error formula, find out the standard error.
