Question

Write the definition of standard deviation.

Answer

Standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance. The standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean.
$\sigma=\sqrt{\sum_{i=1}^n \frac{(x i-\bar{x})^2}{n}}$
