# Mathematical statistics of goals - Ice Hockey. Olympic Games (FT)

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

Quantity of matches (sample size) : 138, period of time : 02-16-2010 - 02-20-2022

### Match total

Average per match E = 5.09, variance V = 6.42, SD = 2.53, E/V = 0.79, Min = 0, Max = 12
P1 = 62.3%, draw = 16.7%, P2 = 21.0%, total 0 = 0.7%, over 2.5 = 82.6%, under 2.5 = 17.4%
Basic random variable ~ Poisson distribution: Pois(E)  ### Home team goals

Average per match E = 3.18, variance V = 5.05, SD = 2.25, E/V = 0.63, 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 = 1.91, variance V = 2.58, SD = 1.61, E/V = 0.74, Min = 0, Max = 8
Basic random variable ~ Poisson distribution: Pois(E) and authentic random variable ~ Severyn distribition: Sever(E, V) ••• ### Goals difference

Average per match E = 1.28, variance V = 8.86, SD = 2.98, E/V = 0.14, Min = -8, Max = 10
