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






2. 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






3. 31 cards (1 blank and 30 pictures) with interpersonal scenes (2 people facing each other); subject tells story about each which reveals aspects of personality; often measure need for achievement; interpreting terms include needs - press - personology






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






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






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






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






8. Used most commonly on standardized test






9. 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






10. 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






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






12. Measure the extent to which test measures what it intends to; concurrent - construct - content - face






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






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






15. Studying the same objects at different points in the lifespan and provides better - more valid results than most other methods - costly - time commitment






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






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






18. 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






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






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






21. Measure how well you know a subject - measure past learning






22. Subjects alter behaviour because they are being observed






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






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






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






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






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






28. Knowing how to do something






29. 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






30. 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






31. Use correlation coefficients in order to predict one variable y from another variable x - let you define a line on graph that describes the relationship between x and y - when the least-square line or regression line is fit to the data - basically: u






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






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






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






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






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






37. Internal-External Locus of Control Scale






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






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






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






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






42. For children 4-6






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






44. 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






45. 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






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






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






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






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






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