Mathematical statistics of goals - Ice Hockey (FT)

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

Quantity of matches (sample size) : 65024, period of time : 09-04-2012 - 05-09-2022

Match total

Average per match E = 5.49, variance V = 6.17, SD = 2.48, E/V = 0.89, Min = 0, Max = 28
P1 = 46.6%, draw = 19.8%, P2 = 33.6%, total 0 = 0.6%, over 2.5 = 89.9%, under 2.5 = 10.1%
Basic random variable ~ Poisson distribution: Pois(E)
