SpletThe independence is used in E(XY)=E(X)E(Y). This translates to the standard deviation as σ_{X+Y}=√(σ_X²+σ_Y²) which fits well with the eulicidian norm (think throwing darts at a darts board, X being the variation in x direction, Y the in y direction), then σ_{X+Y} gives the standard deviation of the radius. SpletThe mean deviation is defined as a statistical measure that is used to calculate the average deviation from the mean value of the given data set.
