Variables

Question 1

Variables

Independent variable (IV)

Answer 1

Variable which experimenter manipulates/changes to demonstrate a difference between the experiments; conditions
-Assumed to have a direct effect on the dependent variable

Question 2

Dependent variables

Answer 2

Variable that the experimenter measures

-Depends on the independent variable

Question 3

Operationlisation

Answer 3

Both variables must be fully operationalised- defining precisely how you intend to measure DV and alter conditions of IV. Psychologists are interested in processes of the human mind, hard because we can’t see it
Instead we have to measure people’s behaviour, ensure we have used operationalised definition of the mental processes
