De student heeft haar gegevens correct ingevuld maar geen verder toelichting gegeven.

De student heeft zijn/haar gegevens ingevoerd maar geeft geen toelichting. Het is niet duidelijk wanneer de tijdreeks begint waardoor de vraag is of punt 2 in het mean plot ook gezien kan worden als maand 2, februari. Daarnaast toont de mean plot een aantal maanden die sterk afwijken van het gemiddelde.

Zet idd je gegevens die je invoert (je tijdreeks) bij in je word doc. Zo kunnen we nagaan wanneer je tijdreeks begint en eindigt, of we met maandelijkse observaties zitten of trimestriele...

De gegevens zijn inderdaad correct ingevuld, maar verdere informatie ontbreekt.
