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






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






3. The effect that might result when a group is born and raised in a particular time period






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






5. 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






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






7. Used most commonly on standardized test






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






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






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






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






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






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






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






15. 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






16. The most frequently occurring value






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






18. Overall range or spread - most basic measure of variability - subtracts the lowest value from the highest value in a data set






19. 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






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






21. 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






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






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






24. 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






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






26. Internal-External Locus of Control Scale






27. 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






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






29. 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






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






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






32. Process in testing concurrent validity






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






34. 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






35. 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






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






37. Naturalistic setting - less control over environment than in lab; generates more hypotheses than able to prove






38. For children 4-6






39. Combines longitudinal and cross-sectional approach






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






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






42. 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






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






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






45. 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






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






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






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






49. 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






50. Similar to word association - finish incomplete sentences
