Standard Deviation Calculator

We will apply the sample standard deviation formula below:

$$s=\sqrt{{\displaystyle \frac{\underset{i=1}{\overset{n}{\sum <!--\; \sum \; -->}}(x_i-<!--\; -\; -->\stackrel{¯<!--\; ¯\; -->}{x}{)}^2}{n-<!--\; -\; -->1}}}$$ $$s=\sqrt{{\displaystyle \frac{SS}{n-<!--\; -\; -->1}}}$$
