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






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






3. 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






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






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






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






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






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






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






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






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






12. Tell you the average extent to which scores were different from the mean - if average standard deviation is large - then scores were highly dispersed






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






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






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






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






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






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






19. 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






20. Not to diagnose depression but assess severity of depressive symptoms; used by researcher or clinician to track course of depressive symptoms






21. 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






22. The most frequently occurring value






23. Internal-External Locus of Control Scale






24. Similar to word association - finish incomplete sentences






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






26. 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






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






28. Whether test really taps abstract concept being measured






29. 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






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






31. 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






32. Process in testing concurrent validity






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






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






35. (Mental age/chronological age)/100 - Highest age = 16

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






37. The hypothesis that no real differences or pattern exist






38. Whether test items look like they measure the construct






39. Tests the effects of two independent variables or treatment conditions at once






40. The process of representing or analyzing numerical data






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






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






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






44. Personality measure for 'normal' / less clinical groups than MMPI - by Harrison Gough






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






46. How the score are spread out overall






47. Sorting cards into a normal distribution; each has a different statement on it about personality; to one end is 'least like self' - other is 'most like self' - and middle is neutral; factor analysis to reduce viewpoints into a few factors






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






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






50. 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
