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






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






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






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






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






6. 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






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






8. Revised Binet'S version - used with children - organized by age level - Best known predictor of future academic achievement






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






10. 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






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






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






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






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






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






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






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






18. 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






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






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






21. 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






22. 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






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






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






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






26. Analyses how a large group responded to each item on the measure; weeds out problematic questions with low discriminatory value; increases internal consistency






27. Knowing a fact






28. Cartoons in which one person is frustrating another; asked to describe how the frustrated person responds






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






30. Internal-External Locus of Control Scale






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






32. The process of representing or analyzing numerical data






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






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






35. For ranks; determining the line that describes a linear relationship






36. Process in testing concurrent validity






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






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






39. 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






40. The hypothesis that no real differences or pattern exist






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. Anything that is measured such as height or depression score on a depression scale






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






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






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






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






47. When subjects do and say what they think puts them in a favorable light -ex: reporting they are not racist even if they really are






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






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






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