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 arousal of sympathetic nervous system - stimulated by lying and anxiety






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






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






4. Birth order vs. intelligence; the older - the more intelligent; the more children - the less intelligent; the greater spacing - the more intelligent






5. The process of representing or analyzing numerical data






6. The hypothesis that no real differences or pattern exist






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






8. 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






9. Comparing an individual'S performance on 2 halves of the same test to reveal internal consistency; internal consistency can be increased by item analysis






10. Mathematically combines and summarizes overall effects or findings for a topic; best known for consolidating effectiveness of psychotherapy - can calculate overall effect size or conclusion drawn from a collection of studies; needed when conflicting






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






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






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






14. When relationship inferred when there is none - ex: many people think there is a relationship between physical and personality characteristics - when evidence show there is none






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






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






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






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






19. 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






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






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






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






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






24. 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






25. 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






26. Process in testing concurrent validity






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






28. 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






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






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






31. 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






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






33. Similar to word association - finish incomplete sentences






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






35. Combines longitudinal and cross-sectional approach






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






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






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






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






40. 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






41. For children 4-6






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






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






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






45. A level of <0.05or <0.01 means that chance that seemingly significant errors are due to random variation rather than to true systematic variance is less than 5% or 1%






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






47. Subjects alter behaviour because they are being observed






48. Like a histogram except that the vertical bars do not touch - various columns are separated by space






49. 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






50. Used when equivalent one cannot be isolated
