Box plot and violin plot

The way a strip plot and swarm plot represent data makes comparison difficult. Suppose you want to find out whether the stable or constrictive population type has a higher median BigMac index value. Can you do that based on the two previous example plots?

You might be tempted to think that the constrictive group has a higher median value because of the higher maximum data point, but in fact, the stable group has a higher median value.

Could there be a better plot type for comparing the distribution of categorical data? Here you go! Let's try a box plot:

# Box plotax = sns.boxplot(x="population type", y="dollar_price", data=merged_df2)ax.set_xlabel("Population type")ax.set_ylabel("BigMac index (US$)")plt.show()
