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






2. 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






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






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






5. Have order - equal intervals and a real zero ex: age






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






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






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






9. 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






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






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






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






13. 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






14. 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






15. 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






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






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






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






19. Has plotted points connected by lines - used to plot variables that are continuous (categories without clear boundaries)






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






21. Used most commonly on standardized test






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






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






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






25. Whether test items look like they measure the construct






26. Knowing how to do something






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






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






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






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






31. 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






32. The most frequently occurring value






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






34. Internal-External Locus of Control Scale






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






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






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






38. 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






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






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






41. Birth order vs. intelligence; the older - the more intelligent; the more children - the less intelligent; the greater spacing - the more intelligent






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






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






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






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






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






47. Similar to word association - finish incomplete sentences






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






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






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