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.

A

B

C

D

F

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

G

H

I

L

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}} $

N

O

P

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} $
