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






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






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






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






5. Process in testing concurrent validity






6. Internal-External Locus of Control Scale






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






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






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






10. Measure of fascism or authoritarian personality






11. The process of representing or analyzing numerical data






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






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






14. Similar to word association - finish incomplete sentences






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






16. Rosenthal effect; researchers see what they want to see; minimized in double-blind






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






18. 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






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






20. 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






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






22. Measured by the same individual taking the same test more than once






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






24. Originally used with free association techniques; word called out - subject says next word in mind






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






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






27. Subjects alter behaviour because they are being observed






28. Personality test from Jung'S theory; 93 questions 2 answers each; 4-letter personality type - each letter 1 of 2 possible opposing characteristics: Introverted vs. Extraverted - Sensing vs. Intuition - Feeling vs. Thinking - and - Judgment vs. Percep






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






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






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






32. Fluid intelligence declines with old age while crystallized intelligence does not






33. Used most commonly on standardized test






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






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






36. Knowing how to do something






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






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






39. 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






40. 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






41. 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






42. 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






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






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






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






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






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






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






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






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