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






2. 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






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






4. The hypothesis that no real differences or pattern exist






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






6. Whether test really taps abstract concept being measured






7. Whether test items look like they measure the construct






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


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






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






11. For ranks; determining the line that describes a linear relationship






12. 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






13. The effect that might result when a group is born and raised in a particular time period






14. Organize data by showing it in a meaningful way; do not allow conclusions to be drawn beyond the sample; percentiles - frequency distributions - graphs - measures of central tendency - variability






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






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






17. 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 -






18. For children 6-16






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






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






21. Step beyond correlations; allows not only identification of relationship between 2 variables - also make predictions






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






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






24. Similar to word association - finish incomplete sentences






25. Combines longitudinal and cross-sectional approach






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






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






28. 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






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






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






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






32. 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






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






34. 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






35. 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






36. The degree to which the result from an experiment can be applied to the population and the real world






37. Used when equivalent one cannot be isolated






38. Anything that is measured such as height or depression score on a depression scale






39. Process in testing concurrent validity






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






41. Inactive substance or condition disguised as a treatment substance or condition - used to form control group






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






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






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






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






46. Not IQ - It is unlikely IQ captures all facets of it






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






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






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






50. How the score are spread out overall
