Controlled Experiments and Variables

Controlled Experiment  a set of compared investigations in which one variable is manipulated by steps while all other variables are controlled or kept the same.

Variable  anything you can change in an experiment that might affect the outcome

F. Y. I.  There are three different types of variables!

#1 Independent or Manipulated Variable:  the variable you purposely change and test

#2 Dependent or Responding Variable:  the factor you measure in response to what you changed

#3 Constant (Controlled) Variable: Constant (Controlled) Variable:  the factors or conditions that are all kept the same (constant) in an experiment

Control Test  What is used to compare the test results, the “normal” situation.  A test that is matched as closely as possible with an experimental test, but is not exposed to any experimental changes.  The results of the experimental tests will be compared to the control test.
