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

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

Quantity of matches (sample size) : 315, period of time : 04-17-2011 - 05-05-2023

### Match total

Average per match E = 6.13, variance V = 7.23, SD = 2.69, E/V = 0.85, Min = 0, Max = 17
P1 = 51.1%, draw = 10.5%, P2 = 38.4%, total 0 = 0.3%, over 2.5 = 94.3%, under 2.5 = 5.7%
Basic random variable ~ Poisson distribution: Pois(E)  ### Home team goals

Average per match E = 3.34, variance V = 5.81, SD = 2.41, E/V = 0.58, 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 = 2.79, variance V = 4.88, SD = 2.21, E/V = 0.57, Min = 0, Max = 12
Basic random variable ~ Poisson distribution: Pois(E) and authentic random variable ~ Severyn distribition: Sever(E, V) ••• ### Goals difference
