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. Whether content covers a good sample of construct being measured






2. 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%






3. Cartoons in which one person is frustrating another; asked to describe how the frustrated person responds






4. The most frequently occurring value






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






6. 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






7. Neither purely descriptive nor purely inferential - can only show relationship - not causality - positive and negative correlation






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






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






10. Consist of vertical bars in which the sides of the vertical bars touch - useful for discrete variables that have clear boundaries - interval variables in which there is some order






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






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






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






14. 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






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






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






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






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






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






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






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






22. Combines longitudinal and cross-sectional approach






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






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






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






26. Knowing a fact






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






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






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






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






31. Whether test items look like they measure the construct






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






33. 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






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






35. 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






36. For children 6-16






37. 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






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






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. 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






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






42. Subjects alter behaviour because they are being observed






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






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






45. 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






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






47. (Mental age/chronological age)/100 - Highest age = 16

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183

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