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






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






3. 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






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






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






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






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






8. The most frequently occurring value






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






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






11. 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






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






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






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






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






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






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






18. 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%






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






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






21. How the score are spread out overall






22. 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






23. Critical of personality trait-theory and personality tests; felt situations (not traits) decide actions






24. 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






25. Measure of fascism or authoritarian personality






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






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






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






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






30. 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






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






32. 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






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






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






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






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






37. Used most commonly on standardized test






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






39. 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






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






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






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






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






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






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






46. Measure innate ability to learn (debatable) - to predict later performance






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






48. 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






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






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