experiment refers to research method that can establish causation by manipulating the variables in question and controlling for alternative explanations of any observed effects.


Other /More definition:
Experiment is defined as a research technique in which an investigator introduces a change into a process in order to make measurements or observations that evaluate the effects of the change; a type of research in which a researcher randomly assigns people to two (2) or more conditions, varies the treatments that people in each condition are given, and then measures the effect on some response.

Moreover, Experiment is defined as:

  1. formal trial undertaken to confirm or disconfirm a hypothesis about cause and effect.
  2. the systematic manipulation of some factors in the environment to observe the effect of this manipulation on behavior
  3. test of a scientific theory in which the researcher manipulates the independent variable.
  4. research method that can establish causation by manipulating the variables in question and controlling for alternative explanations of any observed effects; research method in which the investigator manipulates an (independent) variable under carefully controlled conditions and observes whether there are changes in a second (dependent) variable as a result.
