It indicates how spread out the data points are from the mean. ==Definition== The standard deviation is the square root of variance and is given by: *'''Population Standard Deviation (σ):''' **σ = √[(1/n) * Σ (xᵢ - μ)²] *'''Sample Standard Deviation (s):''' **s = √[(1/(n-1)) * Σ (xᵢ - x̄)²] where: *'''xᵢ''' – Each data point. *'''..." 최신 태그: 시각 편집

It indicates how much the values in a dataset deviate from the average value. ==Definition== The variance (σ²) of a dataset with n elements is calculated as: *Population Variance (σ²): **σ² = (1/n) * Σ (xᵢ - μ)² *Sample Variance (s²): **s² = (1/(n-1)) * Σ (xᵢ - x̄)² where: *'''xᵢ''' – Each data point. *'''μ''' – Population mean. *'''x̄'''..." 최신 태그: 시각 편집

It helps investors understand how much excess return they are earning for the additional risk taken compared to a risk-free asset. ==Definition== The Sharpe Ratio is calculated as: *Sharpe Ratio = (R_p - R_f) / σ_p where: *'''R_p''' – Return of the portfolio. *'''R_f''' – Risk-free rate (e.g., U.S. Treasury rate). *'''σ_p''' – Standard deviation of the portfolio's..." 최신 태그: 시각 편집
