What is the placebo effect ?
A change that occurs in response to expectations about the effectiveness of a treatment, but that actually has no pharmaceutical effects
What is replication ?

What are subjects ?

What is a theory ?

What is validity ?
Having the quality of being founded on fact or evidence
What is a variable?

Types of research designs
- Cross sectional studies
