WebMar 7, 2016 · The calculation of the mean involves summing up all values in a distribution (set of values) and dividing the sum by the number of data points in the distribution. x ¯ = ( ∑ i = 1 n x i) / n One way to understand the rationale behind this calculation is to think of each data point as apples (or some other fungible item). WebJan 5, 2024 · the sampling distribution for the sample mean, X ¯, is derived using the relation Σ X i = n X ¯ as follows: h ( x ¯) = P ( X ¯ = x ¯) = P ( Σ X i = n x ¯) = g ( n x ¯) = e − n λ ( n λ) n x ¯ ( n x ¯)! where x ¯ ∈ { 0, 1 n, 2 n... } For n ≠ 1 This is not a poisson distribution as the pdf is not of the form e − λ λ x ¯ x ¯!.
