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. The hypothesis that no real differences or pattern exist






2. 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






3. 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






4. Measure of fascism or authoritarian personality






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






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






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






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






9. Combines longitudinal and cross-sectional approach






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






11. For children 4-6






12. (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


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






14. Numerically calculating and expressing correlation - r range -1 to +1 - 0 = no relationship






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






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






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






18. 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 -






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






20. Knowing how to do something






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






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






23. Whether test items look like they measure the construct






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






25. 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






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






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






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






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






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






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






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






33. 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






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






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






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






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






38. 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






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






40. 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






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






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






43. 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






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






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






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






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






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






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






50. 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
