In an experiment there are two variables; the Independent Variable (IV) and the Dependent Variable (DV). In the most basic sense, you need two variables because as a researcher, you want to be able to examine if something (a drug, a therapy, a teaching technique, whatever) has an effec...

Independent variables also have different levels. In some experiments, there may only be one level of an IV. In other cases, multiple levels of the IV may be used to look at the range of effects that the variable may have. In an experiment on the effects of the type of diet on weight...
