Psychology dissertation questions students ask

How many participants does a psychology dissertation need?
It depends on your design and expected effect size. Run a power calculation early — your methodology lab notes should record it.
Can I study a clinical population?
Usually not at undergraduate level. Reframe with a non-clinical sample and a validated sub-clinical measure.
