Count data refers to a type of quantitative data that represents the number of times an event occurs within a given observation period or space. This type of data is often non-negative integers and is used in various fields, particularly when modeling occurrences that are random and independent, such as the number of emails received in a day or the number of customers entering a store. Understanding count data is crucial for applying appropriate statistical models, especially when dealing with phenomena that can be described by distributions like the Poisson distribution.
