Types Of Experiments

Question 1

What is ecological validity

Answer 1

Research participants act the way they normally would

Question 2

What is reliability?

Answer 2

Experiment can be replicated with similar results

Question 3

Laboratory experiments

Answer 3

And experiment that is carried out in a controlled environment whether independent variable is manipulated and extraneous variables are controlled

Question 4

Disadvantages of Lab experiments

Answer 4

Reduced ecological validity

People are often were required to behave in ways that are artificial

Question 5

What are the advantages of Lab experiments

Answer 5

High level of control also can easily be replicated

Question 6

Field experiments

Answer 6

And experiment that takes place outside the lab environment where the independent variable is manipulated

Question 7

Advantages of field experiments

Answer 7

Cause and effect relationships can be uncovered

Higher levels of ecological validity is that a true/lab experiment

Question 8

Disadvantages of field experiments

Answer 8

Reduced control also often more time-consuming

Ethical issues if the participants do not know the are being experimented on

Question 9

Natural and quasi- experiments

Answer 9

Natural experiment -experiment where naturally occurring changes in the independent variable obsessive

Quasi-experiment is an experiment where participants cannot be randomly assigned to experimental and control groups

Question 10

Advantages of natural and quasi experiments

Answer 10

You so it would be impractical impossible to manipulate variables

Question 11

Disadvantages of natural and quasi-– experiments

Answer 11

Not always possible to clearly identify cause and effect relationships
