Whats the difference between a poisson and a gaussian distribution??
The biggest difference is that the Gaussian distribution is for a continuous random variable that covers the range -infinity to +infinity. The Poisson distribution models a discrete random variable that is always positive. Perhaps you meant to ask the difference between the Binomial distribution and the Poisson distribution both of which model discrete random variables? If so then the difference is that the Poisson models the number of events in a fixed interval whereas the Binomial models the individual events. ——————————- consider car speed as the random variable Use the Binomial/Normal distribution to model variation in individual car speeds. Use the Poisson distribution to model the number of cars that pass a given point in a fixed time interval.
