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. Used most commonly on standardized test






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






3. 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%






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






6. 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






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






8. The process of representing or analyzing numerical data






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






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






11. 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






12. Knowing how to do something






13. 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 -






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






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






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






17. 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






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






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






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






21. Transformation of a z-score - mean is 50 and the SD is 10 - T=10(Z)+50






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






23. Not to diagnose depression but assess severity of depressive symptoms; used by researcher or clinician to track course of depressive symptoms






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






25. The age level of a person'S functioning according to the IQ test






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






27. Mean is 0 - and SD=1 - This with Z-score allow you to compare one person'S score on two different distributions






28. 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






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






30. Similar to word association - finish incomplete sentences






31. 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






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






33. Whether content covers a good sample of construct being measured






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






35. For children 4-6






36. 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






37. 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






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






39. Subjects alter behaviour because they are being observed






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






41. Studying the same objects at different points in the lifespan and provides better - more valid results than most other methods - costly - time commitment






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






43. The most frequently occurring value






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






45. Measure of fascism or authoritarian personality






46. 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%






47. Like a histogram except that the vertical bars do not touch - various columns are separated by space






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






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






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