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






2. 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






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

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






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






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






7. 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






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






9. 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






10. Process in testing concurrent validity






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






12. Neither the subject nor the experimenter know whether the subject is assigned to the treatment or the control group






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






14. 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






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






16. 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






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






18. 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






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






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






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






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






23. Critical of personality trait-theory and personality tests; felt situations (not traits) decide actions






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






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






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






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






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






30. 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






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






32. 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






33. 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






34. Combines longitudinal and cross-sectional approach






35. How the score are spread out overall






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






37. Organize data by showing it in a meaningful way; do not allow conclusions to be drawn beyond the sample; percentiles - frequency distributions - graphs - measures of central tendency - variability






38. Every member of the population has an equal chance of being chosen for the sample






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






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






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






42. For children 6-16






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






44. 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






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






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






47. 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






48. 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






49. The most frequently occurring value






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