SUMMARY
The discussion clarifies the fundamental properties of the Poisson distribution, specifically that the mean (μ) is equal to the variance (σ²). A variation coefficient of 0.5 is not applicable to a Poisson distribution, as it contradicts the definition where μ must equal σ. The confusion arose from mixing up variance and standard deviation, which are distinct concepts in statistical analysis.
