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. 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






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






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






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. 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






6. 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






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






8. Whether test really taps abstract concept being measured






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






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






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






12. Personality test from Jung'S theory; 93 questions 2 answers each; 4-letter personality type - each letter 1 of 2 possible opposing characteristics: Introverted vs. Extraverted - Sensing vs. Intuition - Feeling vs. Thinking - and - Judgment vs. Percep






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






14. Attitude change in response to feeling that options are limited; e.g. dislike experiment and intentionally behaving unnaturally - or being set on a certain flavour of ice cream as soon as told it is sold out






15. (Mental age/chronological age)/100 - Highest age = 16

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






17. Whether test items look like they measure the construct






18. Used most commonly on standardized test






19. How the score are spread out overall






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






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






22. For even number of values in the set - take the average of the two middle value






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






24. Organize data by showing it in a meaningful way; do not allow conclusions to be drawn beyond the sample; percentiles - frequency distributions - graphs - measures of central tendency - variability






25. Process in testing concurrent validity






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






27. Used when equivalent one cannot be isolated






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






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






30. 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






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






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






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






34. The hypothesis that no real differences or pattern exist






35. Used when n-cases in a sample are classified into categories or cells - tell us whether the groups are significantly different in size - look at the pattern or distributions - not difference between mean - ex:intro psych class categorized into race -






36. The process of representing or analyzing numerical data






37. Combines longitudinal and cross-sectional approach






38. 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






39. 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






40. 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






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






42. 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






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






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






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






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






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






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






49. For children 4-6






50. 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%
