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






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






3. Internal-External Locus of Control Scale






4. Knowing a fact






5. Measures the extent to which items in a measure 'hang together' and test the same thing






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






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






8. 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






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






10. 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%






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






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






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






14. 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






15. There is a general factor in intelligence 'g'






16. Used when equivalent one cannot be isolated






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. Subjects alter behaviour because they are being observed






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






20. The hypothesis that no real differences or pattern exist






21. How a researcher attempts to examine a hypothesis - different questions call for different approaches - some approaches are more scientific than others






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






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






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






25. Combines longitudinal and cross-sectional approach






26. Bell curve; larger the sample - greater chance of having a normal distribution






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






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






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






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






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






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






33. Interest in the effect of independent variable on the dependent variable - often manipulated by applying it in experimental or treatment condition and withholding it from control condition






34. Neither purely descriptive nor purely inferential - can only show relationship - not causality - positive and negative correlation






35. Used most commonly on standardized test






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






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






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






39. Whether test items look like they measure the construct






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






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






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






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






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






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






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






47. The degree to which an independent variable can predict a dependent variable






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






49. The most frequently occurring value






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