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. Takes place in controlled setting must be able to control for: independent variable - dependent variable - and confounding variable






2. When relationship inferred when there is none - ex: many people think there is a relationship between physical and personality characteristics - when evidence show there is none






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






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






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






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






7. Measure of fascism or authoritarian personality






8. 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






9. 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






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






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






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






13. 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






14. Order - variables need to be arranged by order (not necessarily equally spaced) - ex: maranthon finishers






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






16. 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






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






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






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






20. The most frequently occurring value






21. 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






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






23. 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






24. Knowing how to do something






25. When subjects act in ways they think experimenter wants or expects






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






27. 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






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






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






30. 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






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






32. 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






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






34. Developed concept of IQ and first intelligence test (Binet Scale)






35. Used most commonly on standardized test






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






37. 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 -






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






39. Similar to word association - finish incomplete sentences






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. For children 6-16






42. 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






43. Anything that is measured such as height or depression score on a depression scale






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






45. Overall range or spread - most basic measure of variability - subtracts the lowest value from the highest value in a data set






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






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






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






49. figure out how much each score differs (deviates) from the mean by subtracting the mean from each score - square each of these deviation values (to get rid of negative value) - add all these squared deviations to get the sum of square - divide sum by






50. 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
