# 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) : 90, period of time : 02-16-2010 - 02-25-2018

### Match total

Average per match E = 5.08, variance V = 6.27, SD = 2.50, E/V = 0.81, Min = 0, Max = 12
Basic random variable ~ Poisson distribution: Pois(E)  ### Home team goals

Average per match E = 3.23, variance V = 4.47, SD = 2.11, E/V = 0.72, Min = 0, Max = 8
Basic random variable ~ Poisson distribution: Pois(E) and authentic random variable ~ Severyn distribition: Sever(E, V) ••• ### Away team goals

Average per match E = 1.84, variance V = 2.69, SD = 1.64, E/V = 0.68, 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 = 1.39, variance V = 8.06, SD = 2.84, E/V = 0.17, Min = -8, Max = 8
