import pandas as pd
df = pd.read_csv("StudentsPerformance.csv")
df.lunch.value_counts(normalize=True)['free/reduced']
res = df.groupby("lunch", as_index=True).agg(["mean", "var"]).rename(columns={"math score": "math", "reading score": "reading", "writing score":"writing"})

But apparently due to the hierarchical structure, it was not possible to make the same histograms. Please tell me how to hand it over?
