Question

characteristics of poisson distribution​

Answer 1

Answer:

⇒ It is uni-parametric in nature. As we can see, only one parameter λ is sufficient to define the distribution.

⇒ The mean of  X∼P(λ) is equal to λ.

⇒ The variance of X∼P(λ) is also equal to λ. The standard deviation, therefore, is equal to +√λ.
