What is a statistical distribution

A probability distribution is a mathematical function that provides the probabilities of the occurrence of various possible outcomes in an experiment. Probability distributions are used to define different types of random variables in order to make decisions based on these models. There are two types of random variables: discrete and continuous. Depending on what category the random variable fits into, a statistician may decide to calculate the mean, median, variance, probability, or other statistical calculations using a different equation associated with that type of random variable. This is important because, as experiments may become more complicated, the standard formulas that are used to calculate these parameters (like the mean) will no longer produce accurate results.
