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. Does not control - but examines how independent variable affects it






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






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






4. 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 -






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






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






7. 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






8. For children 6-16






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






10. 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






11. Internal-External Locus of Control Scale






12. How a researcher attempts to examine a hypothesis - different questions call for different approaches - some approaches are more scientific than others






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






14. Most commonly used for adults 16+ - organized by subtests with subscales and identify problem areas; current is WAIS-IV






15. Similar to word association - finish incomplete sentences






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






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






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






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






20. 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






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






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






23. 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






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






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






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






27. 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






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






29. Whether test really taps abstract concept being measured






30. Notable for cross-cultural application and simple directions - to make the best picture of a man - scored based on detail and accuracy - not artistic talent






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






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






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






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






35. 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






36. 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






37. The process of representing or analyzing numerical data






38. (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


39. Knowing how to do something






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






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






42. 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






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






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






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






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






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






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






49. Capable of showing order and pacing because equal spaces lie between the values - do not include real zero - ex: temperature






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