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






2. How the score are spread out overall






3. Step beyond correlations; allows not only identification of relationship between 2 variables - also make predictions






4. 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






5. 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






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






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






8. 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






9. Attempt to measure less-defined properties (e.g. intelligence) - check for reliability and validity






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






11. 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






12. Knowing how to do something






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






14. Rosenthal effect; researchers see what they want to see; minimized in double-blind






15. 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






16. Structured - do not allow own answers; more objective than projective tests; not completely objective because most self-reported; Q-sort - Minnesota Multiphasic Personality Inventory (MMPI) - California Personality Inventory (CPI) - Myers-Brigg Type






17. 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






18. Compares 2 groups of people like an experiment - but this is used when it is not feasible or ethical to use random assignment ex: smoker vs. cancer






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






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






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






22. The process of representing or analyzing numerical data






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






24. The hypothesis that no real differences or pattern exist






25. 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%






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






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






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






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






30. 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






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






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






33. Similar to word association - finish incomplete sentences






34. 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






35. Process in testing concurrent validity






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






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






38. Combines longitudinal and cross-sectional approach






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






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






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






42. 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






43. Used most commonly on standardized test






44. 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






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






46. Used when equivalent one cannot be isolated






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






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






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






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