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. Whether content covers a good sample of construct being measured






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






3. Population --> sample/subgroup --> representative and unbiased --> achieved through random sampling --> if it'S not feasible - use convenience sampling instead or stratified sampling






4. Fluid intelligence declines with old age while crystallized intelligence does not






5. Bell curve; larger the sample - greater chance of having a normal distribution






6. 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






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






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






9. 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






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






11. 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






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






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






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






15. 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






16. Created to determine whether a person feels responsible for things that happen (internal) or no control over events in life (external)






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






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






19. For children 6-16






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






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






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






23. 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 -






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






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






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






27. Combines longitudinal and cross-sectional approach






28. The most frequently occurring value






29. Used when equivalent one cannot be isolated






30. Whether test really taps abstract concept being measured






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






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






33. 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






34. Similar to word association - finish incomplete sentences






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






36. Used when an experiment involves more than one independent variable - can separate the effects of different levels of different variables - can isolate main effects - can identify interaction effects - ex: studying effect of brain lesion on problem s






37. The age level of a person'S functioning according to the IQ test






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






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






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






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. 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






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






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






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






46. Step beyond correlations; allows not only identification of relationship between 2 variables - also make predictions






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






48. 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






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






50. 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
