Cramér's V

Cramér's V is a statistical measure used to determine the strength of the association between two categorical variables, such as different categories or groups. It produces a value between 0 and 1, where 0 indicates no association (the variables are independent), and 1 indicates a perfect association (the variables are completely related). For example, it can help assess how strongly a person's favorite color is related to their preferred music genre. Cramér's V provides a clear, standardized way to quantify and compare these relationships across different datasets.
