The Basic Experiment

  • Theory
    • An educated guess about a relationship
    • Typically in generic form, not real specific

      • Variables
        • A variable is any characteristic that can vary or differ either within or between groups
        • Typically there are at least two in all research:
          • Independent – the variable that is manipulated by the experimenter (the input variable)
          • Dependent – the unknown variable that is being measured (the outcome variable)

            • Variables must be defined precisely
