How many times can an event occur?

An event can occur any number of times during a time period. Events occur independently. In other words, if an event occurs, it does not affect the probability of another event occurring in the same time period. The rate of occurrence is constant; that is, the rate does not change based on time.

What is Poisson distribution?

The Poisson distribution is the discrete probability distribution of the number of events occurring in a given time period, given the average number of times the event occurs over that time period.

Is the rate of occurrence constant?

The rate of occurrence is constant; that is, the rate does not change based on time. The probability of an event occurring is proportional to the length of the time period. For example, it should be twice as likely for an event to occur in a 2 hour time period than it is for an event to occur in a 1 hour period.

What is a Poisson experiment?

A Poisson experiment examines the number of times an event occurs during a specified interval. The interval could be anything - a unit of time, length, volume, etc. We might, for example, ask how many customers visit a store each day, or how many home runs are hit in a season of baseball.

What is a Poisson distribution?

The number of successes in a Poisson experiment is referred to as a Poisson random variable. A Poisson distribution is a probability distribution of a Poisson random variable.

What is a Poisson random variable?

A Poisson random variable refers to the number of successes in a Poisson experiment.

What is the average rate of success?

The average rate of success refers to the average number of successes that occur over a particular interval in a Poisson experiment.

What is a Poisson probability?

A Poisson probability refers to the probability of getting EXACTLY n successes in a Poisson experiment. Here, n would be a Poisson random variable.

What is a cumulative Poisson probability?

A cumulative Poisson probability refers to the probability that the Poisson random variable (X) falls within a certain range. For example, consider the probability of getting AT MOST n successes in a Poisson experiment. Here, n would be a Poisson random variable.
