What are the most important and basic aspects of an experiment?
What will be an ideal response?
Answer:
In essence, experimentation involves systematically changing one or more independent variables in order to determine whether changes to the independent variables directly cause changes to occur in one or more dependent variables. So, the most important aspect of an experiment is that an independent variable is consistently changed or manipulated in some way, while a dependent variable is systematically measured. It is important to remember that all participants in the experiment must be randomly assigned to experimental conditions. That is, each subject must have the same chance of being assigned to any of the experimental conditions as any other subject does.
