Explanation

• The standard deviation is the square root of the variance.
• This means that if you take the variance and calculate its square root, you get the standard deviation.

The formula for standard deviation is: σ = √(Σ(xi - μ)^2 / n)

Where:

• σ is the standard deviation
• xi are individual data points
• μ is the mean
• n is the number of data points
