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






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






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






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






5. Combines longitudinal and cross-sectional approach






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






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






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






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






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






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






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






13. 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






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






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






16. Have order - equal intervals and a real zero ex: age






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






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






19. Sorting cards into a normal distribution; each has a different statement on it about personality; to one end is 'least like self' - other is 'most like self' - and middle is neutral; factor analysis to reduce viewpoints into a few factors






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






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






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






23. 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






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






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






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






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






28. 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






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






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






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






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






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






34. Subjects alter behaviour because they are being observed






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






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






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






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






39. Mean (standard error of mean) - median mode; normal and platykuric: equal; positively skewed: mode - med - mean; negatively skewed: mean - med - mode; bimodal: equal mean and med - 2 modes






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






41. For children 4-6






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






43. How the score are spread out overall






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






45. 31 cards (1 blank and 30 pictures) with interpersonal scenes (2 people facing each other); subject tells story about each which reveals aspects of personality; often measure need for achievement; interpreting terms include needs - press - personology






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






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






48. 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






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






50. 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
