IB Psychology HL Internal Assessment Example

The student states a focused aim and explains why the question matters beyond the task itself.

The student describes the background theory accurately and connects it clearly to the procedure.

The student identifies and operationalizes the key variables clearly in the dedicated variables section.

The hypothesis does not fully operationalize the variables in its wording.

The null hypothesis is framed in a way that does not perfectly match a two-condition comparison.

There are a few terminology and precision issues, including inconsistent naming of the processing condition.

The student clearly explains the independent-measures design and why it suits the investigation.

The student identifies the sampling technique and gives a relevant description of the participants.

The student justifies the materials and controls well, especially the use of standardized instructions, quiet conditions, and free recall.

The explanation of allocation is not fully consistent, since the procedure suggests a quasi-random method rather than true random allocation.

Some justifications would be stronger if the student addressed the trade-off between control and generalizability.

The consent discussion includes an assumption that should be checked rather than stated as fact.
