The following box plot represents data on the GPA of 500 students at a high school. Outliers may indicate other conditions in your data. It works like a histogram, but uses kernel smoothing to provide a smoother curve where noise might otherwise be present. Boxplot – Box plot is an excellent way of representing the statistical information about the median, third quartile, first quartile, and outlier bounds. It is really close to a boxplot, but allows a deeper understanding of the distribution. Typically, violin plots will include a marker for the median of the data and a box indicating the interquartile range, as in standard box plots. Note Jon Peck has published a graphboard template to generate violin plots for SPSS, but here I will show how to generate them in the usual GGRAPH commands. Discover complex relationships and improve predictive models. Rather than showing counts of data points that fall into bins or order statistics, violin plots use kernel density estimation (KDE) to compute an empirical distribution of the sample. Another notion is the violin plot, which combines a boxplot and a (doubled) kernel density plot. References. I've created these split half violin plots using ggplot. geom_violin() for examples, and stat_density() for examples with data along the x axis.
