Violin Plots

Violin plots are very similar to box plots; however, violin plots show the distribution of data more visibly than box plots do.

In the following plots, note how graphs appear to get wider near the middle and thinner at the tips. This is how violin plots display data distribution. The wider areas, or the peaks, indicate a large concentration of data are in those areas, while the thinner tips show that there is little data there.

Additionally, you may notice certain points are specifically shown on a violin plot. These points are outliers.

I believe the graphs indicate nothing about the no heart disease group; however, it more indicates that people are more likely to get heart disease as an adult than as a child, since the data peaks at around 55 years of age for males and 60 for females.

For Max Heart Rate, it seems like there may be a correlation between higher heart rate in individuals with heart disease and individuals with no heart disease. However, looking at the female group especially, it appears that the difference may be insignificant due to the large overlap at the peaks of the graphs.
