How does the Poisson Distribution Calculator work?

Free Poisson Distribution Calculator - Calculates the probability of 3 separate events that follow a poisson distribution.
It calculates the probability of exactly k successes P(x = k)
No more than k successes P (x <= k)
Greater than k successes P(x >= k)
Each scenario also calculates the mean, variance, standard deviation, skewness, and kurtosis.
Calculates moment number t using the moment generating function
This calculator has 4 inputs.

What 2 formulas are used for the Poisson Distribution Calculator?

λ p * n
P(k; λ) = λ^k/e^λk!

What 9 concepts are covered in the Poisson Distribution Calculator?

distribution: value range for a variable
event: a set of outcomes of an experiment to which a probability is assigned.
factorial: The product of an integer and all the integers below it
mean: A statistical measurement also known as the average
moment: a function are quantitative measures related to the shape of the functions graph
poisson distribution: a discrete probability distribution that is used to show how many times an event is likely to occur over a specified period.
probability: the likelihood of an event happening. This value is always between 0 and 1.
P(Event Happening) = Number of Ways the Even Can Happen / Total Number of Outcomes
standard deviation: a measure of the amount of variation or dispersion of a set of values. The square root of variance
variance: How far a set of random numbers are spead out from the mean
