Imagine the question, "Which car is faster, Mustang or Camero?
How soon can each car go around a three mile road course? How quickly can each car reach the top of Pike's Peak? The answer to each of these questions may result in a different car being named the "fastest.
For instance, how fast do the vehicles go from zero to sixty. You run several races, different times of day, road conditions, using multiple stop watches, different drivers,etc. You log the results. The only thing constant is that the time logged is at the point the cars reach sixty mph.
The effect will vary according to the influence it has on the subject. A controlled group is necessary for all legitimate studies. It is a group that maintains a constant level of influence from different variables. The control group should attempt to replicate the natural phenomenon. Variables that are constant among the control and experiment groups are termed controlled variables.
The independent variable is the one difference introduced into the experimental group. The experimental group outcome is independent of the control group because of the difference. The independent variable should be limited to a single difference to eliminate crossover contamination. The dependent variable is the observation being measured. It is dependent upon the independent variable.
By reducing the independent variable to one, the dependent variable can be assumed to be caused by the one change. To better understand the interaction let's construct a realistic experiment.
