It is calculated as: Confidence Interval = x +/- tα/2, n-1* (s/√n) where: x: sample mean tα/2, n-1: t-value that corresponds to α/2 with n-1 degrees of freedom s: sample standard deviation n: sample size
WebFeb 19, 2024 · A player with an intra-game goals/game rate that follows Poisson distribution is completely expected. A player who is streaky will likely deviate from this distribution. In other words a streaky player will have more 0 goal games, less 1 goal games, and more multiple goal games than predicted by the Poisson distribution.
