Mark scheme

Marking points from the official mark scheme (Oct/Nov 2025). The mark or mark type is shown in brackets.

1. [L5] Very good evaluation including the named issue.
2. [L5] Thoroughly addresses both strengths and both weaknesses in detail.
3. [L5] Selection of evidence is very thorough and effective.
4. [L5] Strengths include reliability (standardisation), quantitative data, validity, ethics.
5. [L5] Weaknesses include ecological validity, ethics, generalisability, quantitative data.
6. [L5 detailed example for Strength] The procedure was standardised so could be replicated. For example, for every participant the instructions for the line-up identification process were the same, and we know that the cartoon targets were Dora and Diego. Therefore, the study can be tested for reliability.
7. [L5 detailed example for Strength] There were controls in place so they could establish cause and effect/has internal validity.
8. [L5 detailed example for Weakness] The sample came from a participant pool at Eastern Ontario University so they might not represent other people as they could be more motivated to participate (generalisability).
9. [L5 detailed example for Weakness] Ecological validity (Weakness identified and implied from context of other examples).
