\(\hat{\sigma}² \sum_{i=1}^{n} \frac{(x_i-\overline{x})²}{n-1}\)

\(\hat{\sigma}² =\) \(\sqrt{\sum_{i=1}^n\frac{(x_i-\overline{x})^2}{n-1}}\)

\(\hat{\sigma}² = \sum_{i=1}^{n} \frac{|x_i-\overline{x}|}{n}\)

\(\hat{\sigma}² = \sum_{i=1}^{n} \frac{(x_i-\overline{x})²}{n}\)

\(\hat{\sigma}² = \sum_{i=1}^{N} \frac{(x_i-\mu)²}{N}\)
