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






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






3. 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






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






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






6. Used most commonly on standardized test






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






8. Experimenter bias; researchers see what they want to see; minimized in double-blind






9. Whether test really taps abstract concept being measured






10. 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






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






12. Knowing a fact






13. 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






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






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






16. I when incorrectly reject null - thought significant but chance; II when incorrectly accept null - thought chance but significant






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






18. Developed concept of IQ and first intelligence test (Binet Scale)






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






20. Measures the extent to which items in a measure 'hang together' and test the same thing






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






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






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

24. The process of representing or analyzing numerical data






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






26. Whether test items look like they measure the construct






27. 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






28. For children 6-16






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






30. 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






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






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






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






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






35. 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






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






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






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






39. 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






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






41. 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






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






43. 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%






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






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






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






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






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






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






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