quasi experimenter

Question 2

what is a laboratory experiment

Answer 2

a laboratory experiment are conducted in highly controlled environments

It is not always conducted in a laboratory
e.g. could be a classroom where conditions can be well controlled

Question 3

what is a field experiment

Answer 3

in a field experiment, the IV is manipulated in a natural, more everyday setting

Question 4

what is a natural experiment

Answer 4

when the researcher takes advantage of a pre - existing independent variable

This kind of experiment is called “natural” because the variables would have changed even if the experimenter was not interested

NOTE:
The IV itself is natural not the setting itself. The participants may be tested in a lab. In a field experiment however, the setting is natural

Question 5

what is a quasi - experiment

Answer 5

Quasi experiments have an IV that is based on existing differences between people

e.g. age or gender
no one has manipulated this variable but it simple exists

e.g.
if the anxiety levels of phobic and non phobic patients were compared, the IV of having a phobia would not have come about through any experimental manipulation
