IB Psychology SL Internal Assessment Example

The aim is clear, specific, and well-justified in relation to the psychological context of anchoring.

The student explains the Dual Process Model accurately and connects it directly to the mechanism being investigated.

The hypothesis identifies the independent and dependent variables correctly, and the research focus is easy to follow.

The hypothesis would be stronger if the anchor values and measurement unit were explicitly operationalized.

The link between the theoretical model and the investigation could be made even more explicit in terms of why price estimation is vulnerable to anchoring.

The research design is explained rather than merely named, and the student justifies why an independent-groups structure suits the question.

The participant sample is described clearly with relevant demographic details and a sensible rationale for the choice of age group.

The student explains the controlled variables and materials in a way that shows awareness of how consistency supports the investigation.

Alternating participants is not truly random assignment, so the allocation method is methodologically weaker than described.

The justification for the car image is weakened because the vehicle is visibly identifiable as a Mercedes-Benz, which may introduce brand familiarity effects.

Some sampling choices are described well, but the trade-off between practicality and representativeness could be explained more fully.
