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






2. The most frequently occurring value






3. 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






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






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






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






7. There is a general factor in intelligence 'g'






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






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






11. 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






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






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






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






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






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






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






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






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






20. 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






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






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






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






24. 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






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






26. How the score are spread out overall






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






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






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






30. Tell you the average extent to which scores were different from the mean - if average standard deviation is large - then scores were highly dispersed






31. 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






32. 34.13% - 13.59% - 2.02% - 0.26% and - +3 99.74% - +2 97.72% - +1 84.13% - 0 50.00% - -1 15.87% - -2 2.28% - -3 0.26%






33. Measured by the same individual taking the same test more than once






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






35. Subjects alter behaviour because they are being observed






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






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






38. For children 6-16






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






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






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






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






43. 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






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






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






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






47. 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






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






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






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