- 1Independent Variable (IV) (1)This is a variable that is directly manipulated by the researcher.
( gets changed ) - 2Dependant Variable (DV) (1)This is the thing being measured in the experiment and which changes as a result of the IV being manipulated
- 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 - 4Non Directional Hypothesis (3)- Two tailed hypothesis
- Does not state which direction the results will go
- Example : Alcohol affects reaction time - 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. - 6Extraneous Variables (2)- Nuisance Variables
- Unwanted - 72 types of Extraneous Variables- Participant variables
- Situational variables - 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" - 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 - 10Investigator Effect (1)- Ways in which the researchers unconsciously influence the results of the research
- 11How to reduce the Investigator Effects (3)- Use the " Double Blind Procedure "
- Both participant and researcher are unaware of which group they are in
- This therefore prevents bias - 12Standardisation (2)- Involves making sure all subjects are treat the same
- A script is followed
