Use our Sample Standard Deviation Calculator to quickly determine the variability within your dataset. This essential statistical tool helps you understand how individual data points deviate from the mean, providing critical insights into data spread and consistency. Simply input your values to get instant results.
Formula:
The formula for Sample Standard Deviation (s) is:
s = √ ( Σ(xi - &xmacr;)2 ) / (n - 1)
Where:
s = Sample Standard Deviation
xi = Each individual data point
&xmacr; = Sample Mean (average of all data points)
n = Number of data points in the sample
Σ = Summation (sum of all values)
