Q

weakness of quasi experiment

A

-time
-might have to wait for changes over serval years

17
Q

What is a true experiment?

A

-only lab and field experiments are true
-have control over independent variable
- needs a control group and experimental group

18
Q

What is an extraneous variable?

A

Any variable other than the independent variable that can effect the dependent variable

19
Q

what is a cofounding variable?

A

Any variable other than the independent variable that can effect the dependent variable but researchers are unsure of the true source of the change of the dependent variable

20
Q

What is operationalisation?

A

clearly define variables in terms of how they are measured

21
Q

What is a control group?

A

A Control group is a group of participants that are treated normally to give researchers a measure of how people behaviour when not exposed to the experimental conditions.
