# Standard Error Calculator

You can use this Standard Error Calculator to calculate the standard error of the mean for a given set of numbers.

Please provide numbers separated by comma (e.g: 1,2,3,4,5), space (e.g: 1 2 3 4 5) or line break and hit the "Calculate" button to see the results.

## Standard Error Formula

The Standard Error Calculator uses the following formula:

*
SE
_{
x
}
= s / sqrt( n )
*

*
Where:
*

*
SE
_{
x
}
is the standard error of the mean,
*

*
s is the standard deviation of the sample
*

*
n is the sample size.
*

**
Example:
**
Assume the population standard deviation is 36. Calculate the standard error of the mean for a sample size of 49.

**
Solution:
**
s = 36, n = 49

SE
_{
x
}
= s / sqrt( n )

SE
_{
x
}
= 36 / √49

SE
_{
x
}
= 36 / 7 = 5.1428

Therefore, the standard error of the mean for a sample size of 49 is 5.1428
