Statistics - Formulas

Following is the list of statistics formulas used in the Tutorialspoint statistics tutorials. Each formula is linked to a web page that describe how to use the formula.

F

• Factorial - ${n! = 1 \times 2 \times 3 ... \times n}$

M

• Mean Deviation - ${MD} =\frac{1}{N} \sum{|X-A|} = \frac{\sum{|D|}}{N}$

• Mean Difference - ${Mean\ Difference= \frac{\sum x_1}{n} - \frac{\sum x_2}{n}}$

• Multinomial Distribution - ${P_r = \frac{n!}{(n_1!)(n_2!)...(n_x!)} {P_1}^{n_1}{P_2}^{n_2}...{P_x}^{n_x}}$

R

• Reliability Coefficient - ${Reliability\ Coefficient,\ RC = (\frac{N}{(N-1)}) \times (\frac{(Total\ Variance\ - Sum\ of\ Variance)}{Total Variance})}$

• Residual Sum of Squares - ${RSS = \sum_{i=0}^n(\epsilon_i)^2 = \sum_{i=0}^n(y_i - (\alpha + \beta x_i))^2}$
