Mark scheme

Examiner's comment
Most students could suggest two characteristics of field experiments such as taking place in real world settings or that the participant often does not know they are being observed. Students who claimed that field experiments were valid; reliable; representative were required to explain how this was the case to gain credit because such qualities could equally be a feature of other types of experiment or methods of research.
Notes from the mark scheme and report
- 2 marks for each of two characteristics clearly outlined, 1 if only partially outlined
- credited: real-world setting, participants unaware, variables not controlled, consent problems
- claims of validity, reliability or representativeness only credited if explained as specific to field experiments
