As the Mean increases
So as λ increases the Poisson distribution fits the Normal distribution.

Poisson Graphs from the spreadsheet from the lab were selected for simplicity: 4,6,7,8,9,10

λ=.3564

λ=.6035

λ=1.223

λ=2.086

λ=12.09

λ=247.9





Poisson Probability
There is a probability for the frequency of those events to occur. This is know as the Poisson Probability. Here are 3 examples. This is also on the.
