GRE Psychology: Measurement And Methodology

Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. For children 4-6






2. Neither the subject nor the experimenter know whether the subject is assigned to the treatment or the control group






3. Order - variables need to be arranged by order (not necessarily equally spaced) - ex: maranthon finishers






4. How the score are spread out overall






5. Neither purely descriptive nor purely inferential - can only show relationship - not causality - positive and negative correlation






6. Similar to word association - finish incomplete sentences






7. Includes: testable hypothesis - reproducible experiment - operationalized definition (observable and measurable)






8. Data that has been counted rather than measured - usually limited to whole or positive values - ex: group size - number of hospital visit - number of symptoms






9. Like a histogram except that the vertical bars do not touch - various columns are separated by space






10. The effect that might result when a group is born and raised in a particular time period






11. Attempts to eliminate/minimize these - variables in the environment that might also effect the dependent variable and blue the effect of independent variable on the dependent variable






12. Measures the extent to which items in a measure 'hang together' and test the same thing






13. Measure how well you know a subject - measure past learning






14. Different subjects of different ages are compared - faster - easier






15. Measure arousal of sympathetic nervous system - stimulated by lying and anxiety






16. Has plotted points connected by lines - used to plot variables that are continuous (categories without clear boundaries)






17. 34.13% - 13.59% - 2.02% - 0.26% and - +3 99.74% - +2 97.72% - +1 84.13% - 0 50.00% - -1 15.87% - -2 2.28% - -3 0.26%






18. Birth order vs. intelligence; the older - the more intelligent; the more children - the less intelligent; the greater spacing - the more intelligent






19. Personality measure for 'normal' / less clinical groups than MMPI - by Harrison Gough






20. Tell you the average extent to which scores were different from the mean - if average standard deviation is large - then scores were highly dispersed






21. Whether test really taps abstract concept being measured






22. Draw a person of each sex and tell a story about them






23. Bell curve; larger the sample - greater chance of having a normal distribution






24. compares means of 2 different groups to see if the two groups are truly different - analyze differences between means on continuous data - particularly useful with small n - cannot test for difference between more than 2 groups






25. Used when an experiment involves more than one independent variable - can separate the effects of different levels of different variables - can isolate main effects - can identify interaction effects - ex: studying effect of brain lesion on problem s






26. I when incorrectly reject null - thought significant but chance; II when incorrectly accept null - thought chance but significant






27. How a researcher attempts to examine a hypothesis - different questions call for different approaches - some approaches are more scientific than others






28. When subjects do and say what they think puts them in a favorable light -ex: reporting they are not racist even if they really are






29. When subjects act in ways they think experimenter wants or expects






30. Not simple and linear - looks like a curved line - ex: arousal and perfomance - high A --> low P - Low A --> low P - medium A --> high P






31. Might show how often different variables appear; nominal - ordinal - interval - ratio (real zero)






32. Mathematically combines and summarizes overall effects or findings for a topic; best known for consolidating effectiveness of psychotherapy - can calculate overall effect size or conclusion drawn from a collection of studies; needed when conflicting






33. Knowing how to do something






34. Whether content covers a good sample of construct being measured






35. 31 cards (1 blank and 30 pictures) with interpersonal scenes (2 people facing each other); subject tells story about each which reveals aspects of personality; often measure need for achievement; interpreting terms include needs - press - personology






36. Not IQ - It is unlikely IQ captures all facets of it






37. For ranks; determining the line that describes a linear relationship






38. Use correlation coefficients in order to predict one variable y from another variable x - let you define a line on graph that describes the relationship between x and y - when the least-square line or regression line is fit to the data - basically: u






39. Does not control - but examines how independent variable affects it






40. Overall range or spread - most basic measure of variability - subtracts the lowest value from the highest value in a data set






41. Step beyond correlations; allows not only identification of relationship between 2 variables - also make predictions






42. Tests the same person at multiple time points and looks at changes within that person






43. Not intelligence tests; measure sensory and motor development of infants to identify mental retardation; poor predictors of later intelligence






44. Takes place in controlled setting must be able to control for: independent variable - dependent variable - and confounding variable






45. Anything that is measured such as height or depression score on a depression scale






46. Created to determine whether a person feels responsible for things that happen (internal) or no control over events in life (external)






47. Created multitrait-multimethod technique to determine validity of tests






48. Originally to determine mental illness - now for personality; more clinical than CPI; 550 T/F/unsure questions (e.g. 'I would like to ride a horse'); discriminates between disorders; high validity because highly discriminatory items and 3 validity sc






49. Transformation of a z-score - mean is 50 and the SD is 10 - T=10(Z)+50






50. How much variation there is among n number of scores in a distribution
