Ministry of Education, 15th Floor, Mowat Block violin plots separately for each Region, that is, 7 separate charts, showing Violin plots have many of the same summary statistics as box plots: 1. the white dot represents the median 2. the thick gray bar in the center represents the interquartile range 3. the thin gray line represents the rest of the distribution, except for points that are determined to be “outliers” using a method that is a function of the interquartile range.On each side of the gray line is a kernel density estimation to show the distribution shape of the data. Violin plots are similar to histograms and box plots in that they show an abstract representation of the probability distribution of the sample. I have data on the % of clients who met a criterion A violin plot is a combination of a boxplot and a kernel density plot. ‘belongs’ to only 1 Agency and each Agency is a member of only 1 I’ll call out a few important options here.
