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






2. Combines longitudinal and cross-sectional approach






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






4. Naturalistic setting - less control over environment than in lab; generates more hypotheses than able to prove






5. Whether test really taps abstract concept being measured






6. 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






7. 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






8. 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






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






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






11. Used when equivalent one cannot be isolated






12. Personality measure for 'normal' / less clinical groups than MMPI - by Harrison Gough






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






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






15. The degree to which an independent variable can predict a dependent variable






16. Aims to match demographic characteristics to population (i.e. 50% female - etc)






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






18. 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






19. Created to determine whether a person feels responsible for things that happen (internal) or no control over events in life (external)






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






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






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






23. For children 4-6






24. Assess extent interests and strengths match those found by professionals in a particular job field






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






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






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






28. 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






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






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






31. 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






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






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






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






35. 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






36. 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






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






38. Internal-External Locus of Control Scale






39. 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






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






41. 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






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






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






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






45. 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






46. The most frequently occurring value






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






48. Might show how often different variables appear; nominal - ordinal - interval - ratio (real zero)






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






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