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






2. Internal-External Locus of Control Scale






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






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






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






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






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






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






9. Used when equivalent one cannot be isolated






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

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






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






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






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






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






16. 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






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






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






19. Not intelligence tests; measure sensory and motor development of infants to identify mental retardation; poor predictors of later intelligence






20. 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






21. 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






22. 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 -






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






24. Mean is 0 - and SD=1 - This with Z-score allow you to compare one person'S score on two different distributions






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






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






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






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






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






31. For children 4-6






32. Originally to determine mental illness - now for personality; more clinical than CPI; 550 T/F/unsure questions (e.g. 'I would like to ride a horse'); discriminates between disorders; high validity because highly discriminatory items and 3 validity sc






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






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






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






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






37. 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






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






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






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






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






42. Process in testing concurrent validity






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






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






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






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






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






48. Created to determine whether a person feels responsible for things that happen (internal) or no control over events in life (external)






49. 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






50. 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%
