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






2. 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






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






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






5. Similar to word association - finish incomplete sentences






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






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






8. For children 6-16






9. 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






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






11. The most frequently occurring value






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






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. 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 -






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






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






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






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






19. Whether scores on a new measure correlate with other measures known to test the same construct; cross validation process






20. 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






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






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






23. 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






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






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






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






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






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






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






30. Analyses how a large group responded to each item on the measure; weeds out problematic questions with low discriminatory value; increases internal consistency






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






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






33. 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






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






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






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






37. Whether test items look like they measure the construct






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






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






40. Internal-External Locus of Control Scale






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






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






43. 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






44. 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






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






46. Originally to determine mental illness - now for personality; more clinical than CPI; 550 T/F/unsure questions (e.g. 'I would like to ride a horse'); discriminates between disorders; high validity because highly discriminatory items and 3 validity sc






47. Subjects alter behaviour because they are being observed






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






49. Transformation of a z-score - mean is 50 and the SD is 10 - T=10(Z)+50






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