WebCramer's V statistic allows to understand correlation between two categorical features in one data set. So, it is your case. To calculate Cramers V statistic you need to calculate confusion matrix. So, solution steps are: 1. Filter data for a single metric 2. Calculate confusion matrix 3. Calculate Cramers V statistic mario vo filmeIn statistics, Cramér's V (sometimes referred to as Cramér's phi and denoted as φc) is a measure of association between two nominal variables, giving a value between 0 and +1 (inclusive). It is based on Pearson's chi-squared statistic and was published by Harald Cramér in 1946.
