Normal distribution describes continuous data which have a symmetric distribution, with a characteristic 'bell' shape. Binomial distribution describes the distribution of binary data from a finite sample. Thus it gives the probability of getting r events out of n trials.
Sign in. Why did Poisson have to invent the Poisson Distribution? When should Poisson be used for modeling? To predict the of events occurring in the future! More formally, to predict the probability of a given number of events occurring in a fixed interval of time. It can be how many visitors you get on your website a day, how many clicks your ads get for the next month, how many phone calls you get during your shift, or even how many people will die from a fatal disease next year, etc.

The random variable X is said to have a binomial distribution with parameters n and p; abbreviated. X ∼ Bin(n, p) The Binomial Distribution: Example Check your answers using the standard results E[Y ] = np and Var [Y ] = np(1p).
The probability of a success during a small time interval is proportional to the entire length of the time interval. Apart from disjoint time intervals, the Poisson random variable also applies to disjoint regions of space. We use upper case variables like X and Z to denote random variables , and lower-case letters like x and z to denote specific values of those variables.
In probability theory, the normal distribution or Gaussian distribution is a very common continuous probability distribution. The normal distribution is sometimes informally called the bell curve. Probability density function or p. Here is an example of a p.
Assume that a large Fortune company has set up a hotline as part of a policy to eliminate sexual harassment among their employees and to protect themselves from future suits. This hotline receives an average of 3 calls per day that deal with sexual harassment. Obviously some days have more calls, and some have fewer. We want to model the distribution of calls over the course of an extended period of time.
