  • EXPERIMENT
    • Qualitative Data
      • I.V = Cause D.V = Effect
      • HYPOTHESIS
        • Experimental /Alternative/ Research
          • One Tailed
            • Two-Tailed
              • An effect is predicted by no direction
            • Null
              • No effect is predicted
            • Specific Direction
          • Two-Tailed
            • An effect is predicted by no direction
          • Null
            • No effect is predicted
    • PROCEDURE
    • Subject Variables
      • a) Independent Measures - Different Pp's = Different Conditions
      • b) Repeated Groups - Same Pp's
    • Situational Variables
      • a) Standardisation - Same test conditions, procedure & location
      • b) Randomisation - Randomly allocate to different conditions to avoid experimenter bias
      • c) Counter Balancing - Stop order effect
    • Extraneous Variables
      • Any Variable other than the I.V which may affect the D.V
      • E.V's need to be controlled
        • Subject - Individual differences (age, gender)
        • Situation
