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. 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






2. Knowing how to do something






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






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






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






6. 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






7. Neither the subject nor the experimenter know whether the subject is assigned to the treatment or the control group






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






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






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






11. 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






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






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






14. 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






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






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






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






18. Different subjects of different ages are compared - faster - easier






19. 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 -






20. Calculates how off the mean might be in either direction






21. 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






22. 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






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






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






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






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






27. compares means of 2 different groups to see if the two groups are truly different - analyze differences between means on continuous data - particularly useful with small n - cannot test for difference between more than 2 groups






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






29. A level of <0.05or <0.01 means that chance that seemingly significant errors are due to random variation rather than to true systematic variance is less than 5% or 1%






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






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






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






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






34. Created multitrait-multimethod technique to determine validity of tests






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






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






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






38. For children 4-6






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






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






41. Organize data by showing it in a meaningful way; do not allow conclusions to be drawn beyond the sample; percentiles - frequency distributions - graphs - measures of central tendency - variability






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






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






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






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






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






47. Combines longitudinal and cross-sectional approach






48. 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






49. 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






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