Hands-On Exploratory Data Analysis with Python

Red wine versus white wine

Our output class is the quality column. Based on that column, we can try to find the average quality of each wine as follows:

print("white mean = ",df_white["quality"].mean())print("red mean =",df_red["quality"].mean())

And the output of the code is as follows:

white mean = 5.87790935075541red mean = 5.6360225140712945

As the output says, the average white wine quality is 5.877 and that of red wine is 5.63. The columns in both dataframes are the same.
