Independent variable - the factor that is being tested.
Dependent variable - the factor that will be changed or affected by the independent variable.
Example experiment - If I add fertilizer to my garden, will the plants grow faster?
Independent variable - fertilizer (you are TESTING it to see if it will work or not for your garden)
Dependent variable - rate of plant growth (the thing that you are hoping to CHANGE with the fertilizer is the speed at which the plants will grow).

The dependent variable depends on the independent variables. So in lamens terms the independent variable is steady or the controlled part of the experiment. The dependent variables are the parts that change or the part that is being measured. So the IV is the thing whose value one actively controls and can change, while the dependent variable is the thing whose value then changes as a result. Here is an example: A researcher could compare the frequency and intensity of symptoms (DV or part can not control) when different doses (IV the part you can control) are administered.

A dependant variable changes as a function of some other variable....like the force on your hand held out of a car window is a function of the speed of the car. ... An independant variable is not a function of some other variable.... like the color of your eyes is not a function of the speed or other physical attributes of your car. It's important when solving mathematical equations to analyze physical systems or to design an experiment

Remember this. IV depends on me. DV depends on IV. =)
