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. Whether test items look like they measure the construct






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






3. 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






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






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






6. How much variation there is among n number of scores in a distribution






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






8. 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%






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






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






11. Structured - do not allow own answers; more objective than projective tests; not completely objective because most self-reported; Q-sort - Minnesota Multiphasic Personality Inventory (MMPI) - California Personality Inventory (CPI) - Myers-Brigg Type






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






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






14. 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






15. Used most commonly on standardized test






16. 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






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






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






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






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






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






22. Used when equivalent one cannot be isolated






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






24. Whether test really taps abstract concept being measured






25. 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






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






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






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






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






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






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






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






33. 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






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






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






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






37. 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






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






39. Similar to word association - finish incomplete sentences






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

41. Neither purely descriptive nor purely inferential - can only show relationship - not causality - positive and negative correlation






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






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






44. Combines longitudinal and cross-sectional approach






45. Whether scores on a new measure correlate with other measures known to test the same construct; cross validation process






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






47. Allow generalization from sample to population - statistics (sample) - parameters (population): use statistics to estimate parameters






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






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






50. 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
