Boxplot


A boxplot summarizes the distribution of a numeric variable for one or several groups. It allows to quickly get the median, quartiles and outliers but also hides the dataset individual data points. In python, boxplots are most of time done thanks to the boxplot function of the Seaborn library. Boxplots are also described in the online course.

⏱ Quick start

Seaborn is definitely the best library to quickly build a boxplot. It offers a dedicated boxplot() function that roughly works as follows:🔥

# library & dataset
import seaborn as sns
df = sns.load_dataset('iris')

sns.boxplot( x=df["species"], y=df["sepal_length"] )

⚠️ Mind the boxplot

A boxplot is an awesome way to summarize the distribution of a variable. However it hides the real distribution and the sample size. Check the 3 charts below that are based on the exact same dataset.
