Standard Deviation Calculator

Where is the data from ?: *

We will apply the sample standard deviation formula below:

s = \sqrt{\frac{\sum_{i = 1}^{n} (x_{i} - \bar{x})^{2}}{n - 1}}

s = \sqrt{\frac{S S}{n - 1}}

We will apply the population standard deviation formula below:

σ = \sqrt{\frac{\sum_{i = 1}^{n} (x_{i} - μ)^{2}}{n}}

σ = \sqrt{\frac{S S}{n}}
