Experimental Methods

Independent Variable (IV)

The variable that is manipulated or changed by the researcher in an experiment.

Dependent Variable (DV)

The variable that is measured and affected by the changes in the independent variable.

Lab Experiments

Experiments conducted in a controlled environment to ensure accurate and objective measurements.

Field Experiments

Experiments conducted in the natural environment of participants, allowing for real-life settings with some control over extraneous variables.

Natural Experiments

Investigations where naturally occurring independent variables are studied without deliberate manipulation, often with rare occurrences and non-random participant allocation.
