6. What is the independent variable ?

  • Variable that is changed or controlled to test effect on the dependent variable
  • The variable that is tested and mesasured and is controlled by the dependent variable
  • PAss
  • Something you control

7. What does RV stand for and what is it?

  • Pass
  • Factors that affect the two IV levels differently
  • Random variables . RV's are other factors that could effect the outcome.
  • Factors that could affect the DV in some way creating noise, resulting in unclear measurement

8. What is the FIELD experimental design?

  • Iv manipulated by experimenter, tasks and setting may be unlike real life
  • Iv is manipulated by the experimenter , in a real life setting like hospitals or schools
  • Iv changes occur natually in a real life setting
  • Pass

9. What is Extraneous Variable ?

  • Pass
  • Factors the affect the two IV levels differently, causes mistaken conclusion of what has actually affect the dv
  • Factors that affect the DV, creating noise, resulting in unclear measurements.
  • Other random factors that could effect the outcome

10. In an un-ideal world, what are the 2 options of the cause of the variability ?

  • Variability in DV can only be caused by the IV
  • 1) Variability in DV by the IV 2) Variability in DV caused by systematic or random error.
  • Pass
  • Pass

11. What is systematic error ?

  • Error caused due to human error, cant be helped
  • Pass
  • Affects the score of one condition differently to the other ( confounding variables)
  • Spread randomly across the scores of both conditions ( Extraneous)

12. Reliability is....

  • Whether we can replicate the results - experimental effect is stable and cosistent
  • whether we can replicate the results - experimental effect is consistent and stable

13. What is Confounding Variables?

  • Pass
  • Factors that affect the DV , creating noise resulting in unclear measurement.
  • Factors that could affect the two IV levels differently- causes mistake in conclusion of what had affected DV
  • Other factors that could affect the outcome

14. What is the dependent variable?

  • The variable that is manipulated in the scientific experiment
  • An unexpected variable
  • The variable that is being tested and measured.
  • Pass

15. What is Reliability ?

  • -Experimental effect is consistent and stable. You can replicate the findings.
  • Pass
  • The consistency of the experi
  • Does the experi explain what it clains to explain? How true is causality of the behaviour?

16. Confounding variable which causes systematic errors ...

  • Affects the 2 Iv conditions differently ,
  • Affects the 2 Iv conditions differently

17. What is categorical data?

  • Scores from participants are placed in a category - eg race, gender ,educational level
  • Scores from participants that are placed in categories . Gender, Race, educational level

18. When to use Within participants design ?

  • - Same participants can participate in both conditions. - Use when its hard to recruit participants
  • - Different participants are used in each IV condition ( independent group)
  • Pass
  • Pass

19. What is Validity ?

  • Being able to replicate the findings, Experimental effect is consistent and stable
  • Whether you can you use
  • How true is the causality of the behaviour, does the experi really explain what it claims to explain?
  • Pass

20. Extraneous variable which causes random errors ...

  • are factors that may affect the DV in some way
  • are factors the may affect the DV in some way
