You can use the Poisson distribution to approximate the binomial distribution with mean nP when P is small and n is large,such that nP is of only moderate size (preferably nP ≤ 7).
α
Often represents the level of significance in statistical tests, marking the probability threshold below which the null hypothesis is rejected.
Degrees of Freedom
The quantity of independent variables or measures that can change during the computation of a statistic.
T Distribution
A probability distribution used in statistics that arises when estimating the mean of a normally distributed population in situations where the sample size is small and population standard deviation is unknown.
