What is a Violin Plot?
A violin plot is a combination of a box plot and a kernel density plot, showing the probability density of data at different values. The width of the "violin" represents the frequency of data points at that particular value.
Components of a Violin Plot
- The outer shape shows the kernel density estimation
- The internal box plot shows summary statistics
- Optional points show individual observations or outliers
- Mean and median markers provide central tendency measures
Interpreting Violin Plots
- Width indicates the frequency of values in that region
- Symmetry or asymmetry reveals distribution shape
- Multiple peaks suggest multimodal distributions
- Box plot elements show quartiles and outliers
- Comparing multiple violins shows differences between groups
