  21. What is a variable that you are going to manipulate...change on purpose...during the experiment?
    The Independent variable
  22. What is the variable that may change as a result of your manipulation of other variables?
    Dependent variables
  23. What is something that does not change at all during the experiment?
    The Constant
  24. What is a sample that is treated like the experimental groups except that the independent variable is not applied to it. Like in an experiment that looks at the effect of two different types of exercises, it is the group that does not exercise at all.
