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. 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






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






3. Population --> sample/subgroup --> representative and unbiased --> achieved through random sampling --> if it'S not feasible - use convenience sampling instead or stratified sampling






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






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






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






7. Whether test really taps abstract concept being measured






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






9. How well a test measures a construct; multitrait-multimethod technique determines validity; internal - external: concurrent - construct - content - face






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






11. How the score are spread out overall






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






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






14. 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%






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






16. 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






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






18. 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






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






20. Compares 2 groups of people at the same time point






21. When subjects that drop out are different than those that remain; no longer random






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






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






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. Process in testing concurrent validity






26. Give descriptive names - No order or relationship among the variables other than to separate them into groups - ex: male-female






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






28. Whether test items look like they measure the construct






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






30. 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






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






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






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






34. Knowing how to do something






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






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






37. If it is significant - same finding can be generalized to the population - use test of significant to reject null hypothesis






38. 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






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. Revised Binet scale to Stanford-Binet Intelligence Scale; also studied gifted children - those with higher IQs better adjusted






41. Allow generalization from sample to population - statistics (sample) - parameters (population): use statistics to estimate parameters






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






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






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






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






46. Tests whether at least 2 groups co-vary - can adjust for preexisting differences between groups






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






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






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






50. Internal-External Locus of Control Scale
