Web. Step 1: e is the Euler's constant which is a mathematical constant. Generally, the value of e is 2.718. Step 2: X is the number of actual events occurred. It can have values like the following. x = 0,1,2,3 Step 3: λ is the mean (average) number of events (also known as "Parameter of Poisson Distribution). Web. n = the size of the jth group s = the sum of the values in the jth group n = total number of all the values combined (total sample size: ∑ n ) x = one value: ∑ x = ∑ s Sum of squares of all values from every group combined: ∑ x2 Between group variability: SStotal = ∑ x2 - ( ∑ x 2 ) n Total sum of squares: ∑ x2 - ( ∑ x ) 2 n.
