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. 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






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






3. Measure of fascism or authoritarian personality






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






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






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






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






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






9. 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






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






11. Knowing a fact






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






13. 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






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






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






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






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






18. 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






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






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






21. 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






22. Process in testing concurrent validity






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






24. 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






25. Personality measure for 'normal' / less clinical groups than MMPI - by Harrison Gough






26. Similar to word association - finish incomplete sentences






27. Combines longitudinal and cross-sectional approach






28. 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






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






30. 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






31. 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






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






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






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






35. The hypothesis that no real differences or pattern exist






36. 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






37. Describe what is seen in each of 10 inkblots; scoring is complex; validity questionable






38. 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 -






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






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






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






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






43. Tests the effects of two independent variables or treatment conditions at once






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






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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


46. Measure the extent to which test measures what it intends to; concurrent - construct - content - face






47. 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






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






49. 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






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