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






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






3. compares means of 2 different groups to see if the two groups are truly different - analyze differences between means on continuous data - particularly useful with small n - cannot test for difference between more than 2 groups






4. 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






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






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






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






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






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






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






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






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






13. Allows own answer: expression of conflicts - needs - impulses; content interpreted by administrator - some more objective than others; Rorschach Inkblot Test - Thematic Apperception Test - Rosenzweig Picture-Frustration (P-F) Study - Word Association






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






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






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






17. How the score are spread out overall






18. 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






19. 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






20. 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






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






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






23. 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






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






25. Knowing a fact






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






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






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






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






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






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






32. figure out how much each score differs (deviates) from the mean by subtracting the mean from each score - square each of these deviation values (to get rid of negative value) - add all these squared deviations to get the sum of square - divide sum by






33. 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






34. Naturalistic setting - less control over environment than in lab; generates more hypotheses than able to prove






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






36. 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






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






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






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






40. Measure of fascism or authoritarian personality






41. Whether test items look like they measure the construct






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






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






44. Subjects alter behaviour because they are being observed






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






46. 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%






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






48. Combines longitudinal and cross-sectional approach






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






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