How do I evaluate case studies in IB psychology?

First memorise a mental checklist that can be applied to each case study.-Ecological validity-Generalisability-Ethnocentrism-Ethical considerations-Participant bias-Cross checking facts-Reductionism-Gynocentrism/Androcentrism -Sample size-Data collection process-Researcher biasBut then also when memorising the studies, think what makes that study stand out and if it makes the findings more or less reliable.
