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






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






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






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

5. For children 4-6






6. When subjects act in ways they think experimenter wants or expects






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






8. The process of representing or analyzing numerical data






9. 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






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






11. The hypothesis that no real differences or pattern exist






12. Subjects alter behaviour because they are being observed






13. Knowing how to do something






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






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






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






17. Used when equivalent one cannot be isolated






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






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






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






21. 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






22. Mean of Americans is standardized to 100 - with SD 15 or 16 depending on test; correlates most with IQ of biological parents and socioeconomic status






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






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






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






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






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






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






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






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






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






32. 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






33. Not IQ - It is unlikely IQ captures all facets of it






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






35. 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






36. Whether test really taps abstract concept being measured






37. Knowing a fact






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






39. 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






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






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






42. 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






43. For children 6-16






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






45. 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






46. 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






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. Attitude change in response to feeling that options are limited; e.g. dislike experiment and intentionally behaving unnaturally - or being set on a certain flavour of ice cream as soon as told it is sold out






49. 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






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