          • Controlling Particpant Variables
            • Large sample and randomly seleted to gain representative samples.
            • Use repeated measures design or matched pairs deisgn instead of independent measures design
            • Randomly allocate particpants to condition.
          • Controlling Enviroment variables
            • Standardise: Keep everything the same for partipants
              • Standardised Procedure
              • Standardised Method
            • Controlling for order effects
            • Controlling for Demmand Charactheristics:
              • Deception - lying about the aim
              • Distractor questions/ tasks/actions
              • Sting blid: The particpants is unaqare of which condition they're in.
