Visualizzare la produttività nei blocchi per incentivo

Proseguendo con l’esempio sulla produttività dei lavoratori, esplorerai se i punteggi di produttività sono distribuiti nei dati come ci si aspetterebbe con un’assegnazione casuale del trattamento. Nota che questo è un passaggio precauzionale: l’analisi del trattamento e i risultati sull’impatto dei tre trattamenti non sono ancora stati eseguiti!

seaborn e matplotlib.pyplot, rispettivamente come sns e plt, sono già caricati.
