First we find the mean , which is
Next we find the variance. What we do is we take one number from the data set, subtract it from the mean, then square the result, like so:
We do this for the rest of the numbers, to get
We now add them together and divide them by how many there are, so
The last step is to find the standard deviation, which we get by finding the square root of the variance, so
