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






2. 34.13% - 13.59% - 2.02% - 0.26% and - +3 99.74% - +2 97.72% - +1 84.13% - 0 50.00% - -1 15.87% - -2 2.28% - -3 0.26%






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






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






5. 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






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






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






8. 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






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






10. Similar to T-test - but can measure more than 2 groups






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






12. A level of <0.05or <0.01 means that chance that seemingly significant errors are due to random variation rather than to true systematic variance is less than 5% or 1%






13. For children 4-6






14. Anything that is measured such as height or depression score on a depression scale






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






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






17. Combines longitudinal and cross-sectional approach






18. Whether test items look like they measure the construct






19. Used when equivalent one cannot be isolated






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






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






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






23. 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






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






25. Subjects alter behaviour because they are being observed






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






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






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






29. 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






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






31. The process of representing or analyzing numerical data






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






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






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






35. I when incorrectly reject null - thought significant but chance; II when incorrectly accept null - thought chance but significant






36. Used most commonly on standardized test






37. 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






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






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






40. The most frequently occurring value






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






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






43. When subjects do and say what they think puts them in a favorable light -ex: reporting they are not racist even if they really are






44. Interest in the effect of independent variable on the dependent variable - often manipulated by applying it in experimental or treatment condition and withholding it from control condition






45. 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






46. 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






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






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






49. Most commonly used for adults 16+ - organized by subtests with subscales and identify problem areas; current is WAIS-IV






50. Knowing a fact
