# 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) : 369, period of time : 12-26-2011 - 01-05-2023

### Match total

Average per match E = 6.44, variance V = 8.05, SD = 2.84, E/V = 0.80, Min = 0, Max = 18
P1 = 53.1%, draw = 15.2%, P2 = 31.7%, total 0 = 0.3%, over 2.5 = 93.8%, under 2.5 = 6.2%
Basic random variable ~ Poisson distribution: Pois(E)  ### Home team goals

Average per match E = 3.60, variance V = 6.68, SD = 2.58, E/V = 0.54, 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 = 2.84, variance V = 5.78, 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
