IB Psychology HL Internal Assessment Example

The student clearly states a directional hypothesis and identifies both variables in a way that makes the investigation easy to follow.

The student explains anchoring bias with relevant psychological theory and connects it to the task of estimating Gandhi’s age at death.

The student's aim is clearly stated and linked to a previous study, giving the investigation a clear purpose.

The relevance of the investigation is identified, but it is not fully explained in terms of why the study matters beyond the classroom.

Some terminology is imprecise, which weakens the academic precision of the theory explanation.

The operational definitions would be stronger if they were integrated more directly into the hypotheses.

The student describes an independent-measures design clearly and explains why it fits the study.

The student identifies convenience sampling and relevant participant characteristics, and they explain the practical reason for using that approach.

The student describes the control of key variables and the use of standardized materials and instructions.

The allocation procedure is not described consistently, which weakens the clarity of the design explanation.

The choice of participants would be stronger if the student justified why this age group is appropriate for testing anchoring, not just convenient.

Some materials are described rather than fully justified in relation to their effect on validity.
