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






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






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






4. 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






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






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






7. 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






8. 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






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






10. Combines longitudinal and cross-sectional approach






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






12. The hypothesis that no real differences or pattern exist






13. 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






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






15. Not IQ - It is unlikely IQ captures all facets of it






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






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






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






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






20. 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%






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






22. Knowing how to do something






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






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






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






26. Measure innate ability to learn (debatable) - to predict later performance






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






28. Used most commonly on standardized test






29. 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






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






31. Subjects alter behaviour because they are being observed






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






33. Process in testing concurrent validity






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






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






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






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






38. figure out how much each score differs (deviates) from the mean by subtracting the mean from each score - square each of these deviation values (to get rid of negative value) - add all these squared deviations to get the sum of square - divide sum by






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






40. Whether test really taps abstract concept being measured






41. Data that has been counted rather than measured - usually limited to whole or positive values - ex: group size - number of hospital visit - number of symptoms






42. Use correlation coefficients in order to predict one variable y from another variable x - let you define a line on graph that describes the relationship between x and y - when the least-square line or regression line is fit to the data - basically: u






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






44. The process of representing or analyzing numerical data






45. 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






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






47. 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






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






49. 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






50. Internal-External Locus of Control Scale
