The dice probability calculator is a great tool if you want to estimate the dice roll probability over numerous variants. There are may different polyhedral die included, so you can explore the probability of a 20 sided die as well as that of a regular cubic die. Basic Statistics Formulas Population Measures Mean = 1 n X x i (1) Variance ˙2 = 1 n X (x i x)2 (2) Standard Deviation ˙= r 1 n X (x i x)2 (3) Sampling Sample mean x= 1 n X x i (4) Sample variance s2 x = 1 n 1 X (x i x)2 (5) Std. Deviation s x = r 1 n 1 X (x i x)2 (6) z-score.
