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

2. Knowing how to do something






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






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






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






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






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






8. Not intelligence tests; measure sensory and motor development of infants to identify mental retardation; poor predictors of later intelligence






9. Neither purely descriptive nor purely inferential - can only show relationship - not causality - positive and negative correlation






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






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






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






13. Whether test really taps abstract concept being measured






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






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






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






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






18. The process of representing or analyzing numerical data






19. Whether test items look like they measure the construct






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






21. When people agree with opposing statements; giving tacit agreement






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. 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






24. For children 6-16






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






26. Used most commonly on standardized test






27. 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






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






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






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






31. How the score are spread out overall






32. 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






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






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






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






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






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






38. 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






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






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






41. 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 -






42. 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






43. If it is significant - same finding can be generalized to the population - use test of significant to reject null hypothesis






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






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






46. 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






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






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






49. Subjects alter behaviour because they are being observed






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