De studente heeft een 'goede' tijdreeks gevonden, maar heeft nergens vermeld welke bron ze heeft geraadpleegd en wat voor tijdreeks het is. De studente heeft ook alleen maar de Tukey Lamba berekend. Dit is echter niet voldoende om na te gaan of het hele model al dan niet goed is.

Deze studente heeft slechts 1 nieuw model (PPCC Plot Tukey Lambda) ontworpen om na te gaan of het model correct is. Dit is echter niet voldoende.

De student heeft slechts 1 nieuw modele geproduceerd. Bovendien heeft hij geen feedback of conclusie gemaakt bij de gevonden resultaten.
