Hi I was working thru your example and noticed here:

data-wrangling-pycon/books/pydata-examples/solutions/data_analysis_solution.py

Line 17 in 0c31ffb

df['hourly_kids_median'] = df.groupby('hour')['descendants'].transform(median)

Shouldn't this line

df.groupby('hour')['descendants'].transform(median)

be:

df.groupby('hour')['num_kids'].transform(median)

?
