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

Quantity of matches (sample size) : 230, period of time : 12-09-2012 - 12-18-2019

### Match total

Average per match E = 5.87, variance V = 8.13, SD = 2.85, E/V = 0.72, Min = 0, Max = 18
Basic random variable ~ Poisson distribution: Pois(E)  ### Home team goals

Average per match E = 3.15, variance V = 4.21, SD = 2.05, E/V = 0.75, Min = 0, Max = 10
Basic random variable ~ Poisson distribution: Pois(E) and authentic random variable ~ Severyn distribition: Sever(E, V) ••• ### Away team goals
