Specimen 1, Q3b) - do I need to name fundamental principles to gain a mark?

Hello, I am wondering to what extent it is essential to explicitly name the ethical principle that was not obeyed (Specimen 1, Q3b) to gain a mark. E.g. if I write that the presentation of the survey results was biased, would it count as referring to the lack of objectivity and could get me a mark? To make my question more general - would a relevant point be enough or is it necessary to refer to the theory (model, principles, framework etc.) and explicitly name it to gain a mark? Thank you for advice!
