more
less
Define standard deviation
Using the Standard Deviation and Measures of Spread knowledge points
$$
\sigma = \sqrt{\frac{1}{N}\sum_{i=1}^{N}(x_i - \mu)^2}
$$
Analyze the relationship with concentration
Using the Standard Deviation and Measures of Spread knowledge points
- A smaller standard deviation means individual data points \(x_i\) are closer to the mean \(\mu\).
- Therefore, the data points are more clustered or concentrated around the center.
