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

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

Quantity of matches (sample size) : 290, period of time : 12-09-2012 - 12-17-2022

### Match total

Average per match E = 6.02, variance V = 8.10, SD = 2.85, E/V = 0.74, Min = 0, Max = 18
P1 = 47.6%, draw = 17.6%, P2 = 34.8%, total 0 = 1.7%, over 2.5 = 91.0%, under 2.5 = 9.0%
Basic random variable ~ Poisson distribution: Pois(E)  ### Home team goals

Average per match E = 3.21, variance V = 4.42, SD = 2.10, E/V = 0.73, Min = 0, Max = 11
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 = 4.33, SD = 2.08, E/V = 0.65, Min = 0, Max = 15
Basic random variable ~ Poisson distribution: Pois(E) and authentic random variable ~ Severyn distribition: Sever(E, V) ••• ### Goals difference

Average per match E = 0.40, variance V = 9.40, SD = 3.07, E/V = 0.04, Min = -12, Max = 10
