A laboratory experiment need not take place in a formica sided area. It has to do with the control an experimenter is taking over the study. An experiment is an investigation in which a hypothesis is scientifically tested. In an experiment, an independent variable (the cause) is manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled.

This has to be so that experiments are objective. The views and opinions of the researcher should not affect the results of a study. The aim is to make the data more valid, and avoid contamination by interfering variables, such as distractions for the subjects, and from bias.

The researcher deliberately manipulates the IV, measure the DV and maintains strict control over all other variables.
