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






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






3. Critical of personality trait-theory and personality tests; felt situations (not traits) decide actions






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






5. How the score are spread out overall






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






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






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






9. 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%






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






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






12. 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






13. 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






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






15. Combines longitudinal and cross-sectional approach






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

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






18. For children 6-16






19. Used most commonly on standardized test






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






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






22. 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 -






23. 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






24. Used when equivalent one cannot be isolated






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






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






27. Calculates how off the mean might be in either direction






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






29. Knowing a fact






30. Order - variables need to be arranged by order (not necessarily equally spaced) - ex: maranthon finishers






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






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






33. 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






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






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






36. The most frequently occurring value






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






38. 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%






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






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






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. Sorting cards into a normal distribution; each has a different statement on it about personality; to one end is 'least like self' - other is 'most like self' - and middle is neutral; factor analysis to reduce viewpoints into a few factors






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






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






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






46. Process in testing concurrent validity






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






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






49. 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






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