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






2. Population --> sample/subgroup --> representative and unbiased --> achieved through random sampling --> if it'S not feasible - use convenience sampling instead or stratified sampling






3. 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






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






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






6. For children 4-6






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






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






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






11. 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






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






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






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






15. Process in testing concurrent validity






16. Measure innate ability to learn (debatable) - to predict later performance






17. Internal-External Locus of Control Scale






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






19. Similar to T-test - but can measure more than 2 groups






20. 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






21. 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






22. Knowing how to do something






23. 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






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






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






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






27. 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






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






29. 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






30. Most commonly used for adults 16+ - organized by subtests with subscales and identify problem areas; current is WAIS-IV






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






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






33. Intelligence in relation to performance; pioneered development of psychometrics - 'no intelligence is culture-free'






34. The age level of a person'S functioning according to the IQ test






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






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






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






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






39. The most frequently occurring value






40. Capable of showing order and pacing because equal spaces lie between the values - do not include real zero - ex: temperature






41. 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






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






43. Subjects alter behaviour because they are being observed






44. 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 -






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






46. 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






47. For children 6-16






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






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






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