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






2. 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






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






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






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






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






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






8. 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






9. Internal-External Locus of Control Scale






10. The most frequently occurring value






11. The hypothesis that no real differences or pattern exist






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






13. 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






14. Used most commonly on standardized test






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






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






17. 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 -






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






19. 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






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






21. Measure of fascism or authoritarian personality






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






23. Attempts to eliminate/minimize these - variables in the environment that might also effect the dependent variable and blue the effect of independent variable on the dependent variable






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






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






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






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






28. 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






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






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






31. Critical of personality trait-theory and personality tests; felt situations (not traits) decide actions






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






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






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






35. Combines longitudinal and cross-sectional approach






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






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






38. Process in testing concurrent validity






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






40. 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






41. 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






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






43. 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






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






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






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






47. 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






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






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






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