Key Concepts

Poisson Distribution

The Poisson distribution is a discrete probability distribution that measures the number of events occurring in a fixed interval of time or space, under the assumption that these events occur with a known constant mean rate and independently of the time since the last event. It is commonly used for modeling rare, random events, such as the arrival of customers at a store or the occurrence of errors in documents.

Probability Distribution

A probability distribution is a mathematical function that provides the probabilities of occurrence of different possible outcomes in an experiment. It specifies how the probabilities are distributed over the values of the random variable, allowing us to understand which outcomes are more or less likely. This concept is foundational in both discrete and continuous probability theory and is used in various fields such as statistics, economics, and engineering.

Binomial Distribution

The binomial distribution is a discrete probability distribution that describes the number of successes in a fixed number of independent trials, each with the same probability of success. It is applicable when each trial has exactly two possible outcomes (commonly termed as success and failure) and is used to model scenarios such as flipping a coin or quality control testing where the outcomes follow a binary pattern.

Normal Distribution

The normal distribution, often known as the Gaussian distribution, is a continuous probability distribution characterized by its symmetric, bell-shaped curve centered around the mean. It is fundamental in statistics due to the central limit theorem, which states that under many conditions, the sum of a large number of random variables will approximate a normal distribution, making it applicable in various fields like natural and social sciences.
