Variables

- Independent Variable: variable that is manipulated and has a direct effect on DV.
- Dependent Variable: variable that is measured after making changes to IV.
- Extraneous Variable: variables other than IV that COULD affect the DV.
- Confounding Variables: variables that HAVE affected DV.

2

Control conditions

Condition where IV is not manipulated in order to provide a standard against which experimental conditions can be compared.

3

Lab experiments

- When experiment is carried out in a controlled env. which allows researchers to exert a high level of control over IV and eliminate any EV.
- Participants are randomly allocated to a condition.
- Conducted in an artificial setting.

Advantages of lab studies

1) Very high level of control over IV and conditions.
2)
