Mathematical statistics of runs - Baseball

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

Quantity of matches (sample size) : 34245, period of time : 09-30-2011 - 09-27-2023

Match total - runs

Average per match E = 8.77, variance V = 20.15, SD = 4.49, E/V = 0.44, Min = 1, Max = 38
P1 = 53.5%, draw = 0.0%, P2 = 46.5%, total 0 = 0.0%, over 2.5 = 95.8%, under 2.5 = 4.2%
Basic random variable ~ Negative Binomial (Pascal) distribution: NB(r, p), r=6.76, p=0.44
