Gaussian distribution 

; Mean: \bar{x}=\frac{1}{N} \sum x_i

; Median: The individual value from the collection such that 1/2 the observations are less and 1/2 are greater

; Mode: The most frequently occurring value.

; Variance: \sigma_x^2 = \frac{1}{N-1} \sum (x_i - \bar{x})^2

; Standard Deviation (rms/sigma): \sigma_x = \sqrt{\frac{1}{N-1} \sum (x_i - \bar{x})^2}
