Experiments

Experiments involve the manipulation and measurement of variables.

Lab experiments- Researcher manipulates one variable (independent variable) and looks at what effect it has on the other variable (dependent variable).

Advantages: -Cause and effect relationships can be established.

                     -Allow the researchers to control other variables that may have an effect on the results.   

                     -Bringing participants to a controlled environment makes it easier to study the effects of a single variable.

Disadvantages: - Low ecological validity. (often unlike real life)
