Experimental Methods

Question 1

Variables

Answer 1

• 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.

Question 2

Control conditions

Answer 2

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

Question 3

Lab experiments

Answer 3

• 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.

Question 4

Advantages of lab studies

Answer 4

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

2)
