How to interpret violin plot? What is the purpose or use of the same?
A violin plot plays a similar role as a box and whisker plot. A violin plot is more informative than a plain box plot. While a box plot only shows summary statistics such as mean/median and interquartile ranges, the violin plot shows the full distribution of the data. The wider width of the violin plot implies they are more data points around the region. There is no specific use case where only a violin plot should be used, but it can be used instead of a boxplot if you are interested in knowing the distribution of the data.
