A field experiment involves manipulating an independent variable in a natural setting to determine its effect on a dependent variable. In this case, the independent variable is the use of point-of-purchase displays, and the dependent variable is sales. The researcher is manipulating the placement of displays in five stores while leaving the other ten stores as a control group. Therefore, it is a field experiment rather than a laboratory experiment, survey experiment, cross-sectional experiment, or longitudinal experiment.
