👉 In statistics, a "reoccurrence" refers to a situation where data points occur more than once in the same time period. This is often seen in situations where there are many events occurring at once or when a variable's values change over time. For example, if you have a dataset of sales for different products over time and find that a particular product sells at least four times during a given month, this could be considered a reoccurrence because it occurred more than once in the same period
