Research methods

Types of experiment

Natural experiment
Researcher does not manipulate the Iv, it happens by chance, happens naturally and the researcher takes advantage and goes in to study.
Quasi-experiment
The IV already exists and so participants fall naturally into groups and can't be allocated, e.g.gender

Sampling
-
Opportunity sampling
Participants are often taken when they are present at the same time (in a classroom), doing similar things which could mean they have similar personality types.

Experimental design
Counterbalancing
Controls and balances order effect as it makes each condition of the independent variable(IV) occur in all orders equally
Does not eliminate order effect as there are still separate conditions that participants have to complete
