  1. 1Independent Variable (IV) (1)This is a variable that is directly manipulated by the researcher.
    ( gets changed )
  2. 2Dependant Variable (DV) (1)This is the thing being measured in the experiment and which changes as a result of the IV being manipulated
  3. 3Directional Hypothesis (3)- Its a one tailed hypothesis
    - States that the results will go in one direction
    - Example : The faster you type, the more mistakes you'll make
  4. 4Non Directional Hypothesis (3)- Two tailed hypothesis
    - Does not state which direction the results will go
    - Example : Alcohol affects reaction time
  5. 5Operationalisation (2)- Means that you describe how you will measure each variable ( IV and DV )
    - This allows other people to replicate a study in order to confirm or challenge the results.
  6. 6Extraneous Variables (2)- Nuisance Variables
    - Unwanted
  7. 72 types of Extraneous Variables- Participant variables
    - Situational variables
  8. 8Demand Characteristics (4)- When the participant figures out what the study is about
    - This can influence their behaviour
    - Can act positively in order to please the researcher
    - Can act negatively : this behaviour is called the "SCREW YOU EFFECT"
  9. 9How to reduce Demand Characteristics (3)- Technique called the " Single Blind Procedure"
    - Participants don't know which part of the study they are in
    - Example : In a drugs trial participants don't know whether they have been given the real drug or placebo
  10. 10Investigator Effect (1)- Ways in which the researchers unconsciously influence the results of the research
  11. 11How to reduce the Investigator Effects (3)- Use the " Double Blind Procedure "
