Visualizzare le differenze di durata

Dopo l’analisi della durata dei giocattoli, il team di ricerca vuole che tu visualizzi la distribuzione dei punteggi di durata sia per i giocattoli Educational sia per quelli Recreational. Queste visualizzazioni possono offrire insight intuitivi sui dati, evidenziando il range e la variabilità dei punteggi in ciascuna categoria. Questo passaggio è fondamentale per presentare i risultati a stakeholder non tecnici e per guidare le decisioni sullo sviluppo del prodotto.

I dati sono disponibili nel DataFrame toy_durability, e seaborn e matplotlib.pyplot sono già caricati rispettivamente come sns e plt.

Istruzioni dell'esercizio

Visualizza la distribuzione di 'Durability_Score' per i giocattoli Educational e Recreational usando un grafico Kernel Density Estimate (KDE), mettendo in evidenza le differenze colorando in modo diverso le distribuzioni tramite la colonna 'Toy_Type'.

Esercizio pratico interattivo

Prova a risolvere questo esercizio completando il codice di esempio.

# Visualize the distribution of Durability_Score for each Toy_Type
sns.____(data=____, x="____",
