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. Tests whether the means on one outcome or dependent variable are significantly different across groups - height or level of anxiety from anxiety scale






2. For children 6-16






3. Knowing how to do something






4. The approach to construct assessment instruments - involves selection of items that can discriminate between various groups; responses determine if he is like a particular group or not; e.g. Strong-Campbell Interest Inventory






5. 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






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






7. 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






8. 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






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






10. 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






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






12. 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%






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






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






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






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






17. 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 -






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






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






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






21. Give descriptive names - No order or relationship among the variables other than to separate them into groups - ex: male-female






22. Measure how well you know a subject - measure past learning






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






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






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






26. 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






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


28. Analyses how a large group responded to each item on the measure; weeds out problematic questions with low discriminatory value; increases internal consistency






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






30. Does not control - but examines how independent variable affects it






31. Used most commonly on standardized test






32. 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






33. 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






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






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






36. 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






37. figure out how much each score differs (deviates) from the mean by subtracting the mean from each score - square each of these deviation values (to get rid of negative value) - add all these squared deviations to get the sum of square - divide sum by






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






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






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






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






42. 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






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






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






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






46. Subjects alter behaviour because they are being observed






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






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






49. Used when equivalent one cannot be isolated






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