Par où commenceriez-vous votre exploration ?

Premier passage exploratoire sur les données de The Daily Grind. Le propriétaire veut simplement savoir « ce qui mérite d'être creusé ».

Joignez le jeu de données Coffee Sales et testez chacun des quatre points de départ (tendances, distributions, différences, valeurs aberrantes), puis voyez lesquels mettent en évidence quelque chose qui vaut la peine d'être poursuivi.

Quels points de départ ont fait ressortir quelque chose que le propriétaire irait réellement explorer ?
