Experiment models are appropriate for hypothesis testing and explanatory purpose. Example 1: learning about the contribution of aboriginal canadians to. Experiments that occur in the regular course of social events. What are the three components of a classical experiment: independent & dependent variables: an experiment examines the effect of an independent variable on a dependent variable. Typically, the independent variable takes the form of an experimental stimulus. The experimenter compares what happens when the stimulus is present to what happens when it is not: pretesting and posttesting: Pretesting occurs first, whereby subjects are measured in terms of a dependent variable. Then the subject is exposed to a stimulus representing an independent variable. Finally in posttesting, they are remeasured in terms of dependent variable.
