Detailed explanation-1: -In an experiment, the IV is a variable that is changed to see how it affects something else, whereas the DV is a variable that is being measured/observed. The DV is assumed to be affected by the IV, hence the term ‘dependent’ (its value depends on the state of the IV).
Detailed explanation-2: -An independent variable DOES NOT change because of the other variables in the study. On the other hand, a dependent variable DOES change because of other variables. For example, we are interested in how your height changes with time. In this study, there are 2 variables, height and time.
Detailed explanation-3: -Variables in research can also be described by whether the experimenter thinks that they are the cause of a behavior (IV), or the effect (DV). The IV is the variable that you use to do the explaining and the DV is the variable being explained.
Detailed explanation-4: -The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.
