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






2. 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%






3. Used when equivalent one cannot be isolated






4. 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






5. Every member of the population has an equal chance of being chosen for the sample






6. Knowing how to do something






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






8. Notable for cross-cultural application and simple directions - to make the best picture of a man - scored based on detail and accuracy - not artistic talent






9. Empirical-keying or criterion-keying approach; to determine of subject is like a particular group or not






10. Interest in the effect of independent variable on the dependent variable - often manipulated by applying it in experimental or treatment condition and withholding it from control condition






11. Experimenter bias; researchers see what they want to see; minimized in double-blind






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






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






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






15. Numerically calculating and expressing correlation - r range -1 to +1 - 0 = no relationship






16. For children 6-16






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






18. Naturalistic setting - less control over environment than in lab; generates more hypotheses than able to prove






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






20. Attempt to measure less-defined properties (e.g. intelligence) - check for reliability and validity






21. The degree to which an independent variable can predict a dependent variable






22. When subject behave differently just because they thing that they have received the treatment substance or condition






23. 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






24. 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






25. There is a general factor in intelligence 'g'






26. Used most commonly on standardized test






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






28. The degree to which the result from an experiment can be applied to the population and the real world






29. Inactive substance or condition disguised as a treatment substance or condition - used to form control group






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






31. Originally used with free association techniques; word called out - subject says next word in mind






32. How stable measure is; test-retest - split-half






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






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






35. Developed concept of IQ and first intelligence test (Binet Scale)






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






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






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






39. Sorting cards into a normal distribution; each has a different statement on it about personality; to one end is 'least like self' - other is 'most like self' - and middle is neutral; factor analysis to reduce viewpoints into a few factors






40. How the score are spread out overall






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






42. Knowing a fact






43. Whether scores on a new measure correlate with other measures known to test the same construct; cross validation process






44. Compares 2 groups of people like an experiment - but this is used when it is not feasible or ethical to use random assignment ex: smoker vs. cancer






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






46. Intelligence in relation to performance; pioneered development of psychometrics - 'no intelligence is culture-free'






47. 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






48. Tests the effects of two independent variables or treatment conditions at once






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






50. Measure the extent to which test measures what it intends to; concurrent - construct - content - face
