# Mathematical statistics of goals - Ice Hockey. World Championship U20 (FT)

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

Quantity of matches (sample size) : 311, period of time : 12-26-2011 - 12-29-2021

### Match total

Average per match E = 6.40, variance V = 8.05, SD = 2.84, E/V = 0.79, Min = 0, Max = 18
P1 = 53.4%, draw = 14.5%, P2 = 32.2%, total 0 = 0.3%, over 2.5 = 93.6%, under 2.5 = 6.4%
Basic random variable ~ Poisson distribution: Pois(E)  ### Home team goals

Average per match E = 3.59, variance V = 6.46, SD = 2.54, E/V = 0.56, Min = 0, Max = 14
Basic random variable ~ Poisson distribution: Pois(E) and authentic random variable ~ Severyn distribition: Sever(E, V) ••• ### Away team goals

Average per match E = 2.81, variance V = 5.76, SD = 2.40, E/V = 0.49, Min = 0, Max = 16
Basic random variable ~ Poisson distribution: Pois(E) and authentic random variable ~ Severyn distribition: Sever(E, V) ••• ### Goals difference

Average per match E = 0.78, variance V = 16.39, SD = 4.05, E/V = 0.05, Min = -14, Max = 14
