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

Quantity of matches (sample size) : 302, period of time : 12-26-2011 - 01-06-2021

### Match total

Average per match E = 6.39, variance V = 7.96, SD = 2.82, E/V = 0.80, Min = 0, Max = 18
Basic random variable ~ Poisson distribution: Pois(E)  ### Home team goals

Average per match E = 3.62, variance V = 6.60, SD = 2.57, E/V = 0.55, Min = 0, Max = 14
Basic random variable ~ Poisson distribution: Pois(E) and authentic random variable ~ Severyn distribition: Sever(E, V) ••• ### Away team goals
