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. Normal curve - negatively skewed distribution - positively sknewed distribution - bimodal distribution - platykuric distribution






2. 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






3. 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






4. The approach to construct assessment instruments - involves selection of items that can discriminate between various groups; responses determine if he is like a particular group or not; e.g. Strong-Campbell Interest Inventory






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






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






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






8. Used most commonly on standardized test






9. Tests whether the means on one outcome or dependent variable are significantly different across groups - height or level of anxiety from anxiety scale






10. Mean (standard error of mean) - median mode; normal and platykuric: equal; positively skewed: mode - med - mean; negatively skewed: mean - med - mode; bimodal: equal mean and med - 2 modes






11. Revised Binet'S version - used with children - organized by age level - Best known predictor of future academic achievement






12. How the score are spread out overall






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






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






15. Whether test really taps abstract concept being measured






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






17. Consist of vertical bars in which the sides of the vertical bars touch - useful for discrete variables that have clear boundaries - interval variables in which there is some order






18. Fluid intelligence declines with old age while crystallized intelligence does not






19. Frequency polygon (continuous variables) - histogram/ bar graph (discrete)






20. Rosenthal effect; researchers see what they want to see; minimized in double-blind






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






22. Comparing an individual'S performance on 2 halves of the same test to reveal internal consistency; internal consistency can be increased by item analysis






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






24. Describe what is seen in each of 10 inkblots; scoring is complex; validity questionable






25. Measure of fascism or authoritarian personality






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






27. Measured by the same individual taking the same test more than once






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






29. Analyses how a large group responded to each item on the measure; weeds out problematic questions with low discriminatory value; increases internal consistency






30. The most frequently occurring value






31. 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






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






33. Assess extent interests and strengths match those found by professionals in a particular job field






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






35. 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






36. Internal-External Locus of Control Scale






37. Knowing a fact






38. When people agree with opposing statements; giving tacit agreement






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






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






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






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






43. Mean of Americans is standardized to 100 - with SD 15 or 16 depending on test; correlates most with IQ of biological parents and socioeconomic status






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






45. 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






46. 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






47. Subjects alter behaviour because they are being observed






48. Similar to T-test - but can measure more than 2 groups






49. Have order - equal intervals and a real zero ex: age






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