So this is a real simple question for you excel "masters" out there. Excel asks for
POISSON.DIST(x;mean;cumulative)
Now i dont want to poison you with my guess of how it works so instead i'm just going to say that I have an expected value of goals scored for hockey team of 2.8. Assuming goals scored is integer and poisson distribution is correct I want to make a poisson distribution of this. Do I need additional data? What do I enter as input for mentioned excel function?
