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. 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






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






4. Numerically calculating and expressing correlation - r range -1 to +1 - 0 = no relationship






5. How the score are spread out overall






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






7. 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






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






9. Similar to word association - finish incomplete sentences






10. Notable for cross-cultural application and simple directions - to make the best picture of a man - scored based on detail and accuracy - not artistic talent






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






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






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






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






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






16. (Mental age/chronological age)/100 - Highest age = 16

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






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






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






20. Takes place in controlled setting must be able to control for: independent variable - dependent variable - and confounding variable






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






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






23. Created multitrait-multimethod technique to determine validity of tests






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






25. Whether test items look like they measure the construct






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






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






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






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






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






31. 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






32. 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 -






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






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






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






36. 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






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






38. 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






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






40. Has plotted points connected by lines - used to plot variables that are continuous (categories without clear boundaries)






41. 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






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






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






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






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






46. 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






47. 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






48. 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%






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






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