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.

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






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






3. Used most commonly on standardized test






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






5. 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%






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






7. Process in testing concurrent validity






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






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






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






11. Measure of fascism or authoritarian personality






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






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






14. The hypothesis that no real differences or pattern exist






15. The most frequently occurring value






16. Structured - do not allow own answers; more objective than projective tests; not completely objective because most self-reported; Q-sort - Minnesota Multiphasic Personality Inventory (MMPI) - California Personality Inventory (CPI) - Myers-Brigg Type






17. 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

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






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






21. 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






22. 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






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






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






25. 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






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






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






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






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






30. Internal-External Locus of Control Scale






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






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






33. Subjects alter behaviour because they are being observed






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






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






36. 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






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






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






39. 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






40. Every member of the population has an equal chance of being chosen for the sample






41. 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






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






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






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






45. Attempt to measure less-defined properties (e.g. intelligence) - check for reliability and validity






46. How stable measure is; test-retest - split-half






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






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






49. Used when equivalent one cannot be isolated






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