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. 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






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






3. 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






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






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






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






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






9. 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






10. 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






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






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






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






14. Assess extent interests and strengths match those found by professionals in a particular job field






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






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






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






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






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






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






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






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






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






24. 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






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






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






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






28. Knowing how to do something






29. 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






30. 34.13% - 13.59% - 2.02% - 0.26% and - +3 99.74% - +2 97.72% - +1 84.13% - 0 50.00% - -1 15.87% - -2 2.28% - -3 0.26%






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






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






33. Knowing a fact






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






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






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






37. 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






38. 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






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






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






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






42. Not intelligence tests; measure sensory and motor development of infants to identify mental retardation; poor predictors of later intelligence






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






44. Revised Binet scale to Stanford-Binet Intelligence Scale; also studied gifted children - those with higher IQs better adjusted
