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. Number of SD a score is from the mean - For normal distribution - (-3 to +3)






2. 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






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






4. A level of <0.05or <0.01 means that chance that seemingly significant errors are due to random variation rather than to true systematic variance is less than 5% or 1%






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






6. Whether test items look like they measure the construct






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






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






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






10. Subjects alter behaviour because they are being observed






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






12. 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






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






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






15. 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






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






17. Calculates how off the mean might be in either direction






18. Cartoons in which one person is frustrating another; asked to describe how the frustrated person responds






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






20. Allows own answer: expression of conflicts - needs - impulses; content interpreted by administrator - some more objective than others; Rorschach Inkblot Test - Thematic Apperception Test - Rosenzweig Picture-Frustration (P-F) Study - Word Association






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






22. 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






23. Similar to word association - finish incomplete sentences






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






25. Knowing how to do something






26. Aims to match demographic characteristics to population (i.e. 50% female - etc)






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






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






29. Knowing a fact






30. 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






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






32. Process in testing concurrent validity






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






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






35. For children 4-6






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






37. 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






38. When relationship inferred when there is none - ex: many people think there is a relationship between physical and personality characteristics - when evidence show there is none






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






40. 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






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






42. Capable of showing order and pacing because equal spaces lie between the values - do not include real zero - ex: temperature






43. The most frequently occurring value






44. Measure mastery in a particular area (e.g. final exam)






45. Most commonly used for adults 16+ - organized by subtests with subscales and identify problem areas; current is WAIS-IV






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






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






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






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






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