IB Psychology HL Internal Assessment Example

The student states a clear, focused aim and explains why the investigation matters beyond the classroom.

The student describes the theoretical background accurately and connects it to the task in a meaningful way.

The student's hypothesis is testable because both variables are operationalized clearly.

The theory-to-method link could be tightened further by showing more precisely how the time limit affects the judgment process.

The directional logic of the hypothesis could be explained a little more explicitly.

The student identifies an appropriate independent-measures design and explains why it suits the investigation.

The student describes the sampling approach and participant characteristics clearly.

The student includes several relevant controls and materials that support a standardised procedure.

There is a sample-size inconsistency that needs to be corrected.

Some materials and controls are listed more than they are explained.

A few practical implementation choices, such as separate classrooms and different experimenters, are not fully controlled within the design description.
