# Mathematical statistics of goals - Ice Hockey. World Championship (FT)

## Graphs of sample (in blue) and basic random variables (probability density)

Quantity of matches (sample size) : 872, period of time : 04-24-2009 - 05-28-2023

### Match total

Average per match E = 5.47, variance V = 5.45, SD = 2.34, E/V = 1.00, Min = 0, Max = 16
P1 = 50.0%, draw = 17.4%, P2 = 32.6%, total 0 = 0.2%, over 2.5 = 90.6%, under 2.5 = 9.4%
Basic random variable ~ Poisson distribution: Pois(E)  ### Home team goals

Average per match E = 3.06, variance V = 4.33, SD = 2.08, E/V = 0.71, Min = 0, Max = 13
Basic random variable ~ Poisson distribution: Pois(E) and authentic random variable ~ Severyn distribition: Sever(E, V) ••• ### Away team goals

Average per match E = 2.41, variance V = 3.66, SD = 1.91, E/V = 0.66, Min = 0, Max = 12
Basic random variable ~ Poisson distribution: Pois(E) and authentic random variable ~ Severyn distribition: Sever(E, V) ••• ### Goals difference
