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.
