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. Not simple and linear - looks like a curved line - ex: arousal and perfomance - high A --> low P - Low A --> low P - medium A --> high P






2. 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






3. Intelligence in relation to performance; pioneered development of psychometrics - 'no intelligence is culture-free'






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






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






6. Process in testing concurrent validity






7. The degree to which an independent variable can predict a dependent variable






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






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






10. There is a general factor in intelligence 'g'






11. Internal-External Locus of Control Scale






12. For even number of values in the set - take the average of the two middle value






13. 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






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






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






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






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






18. Whether test items look like they measure the construct






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






20. The degree to which the result from an experiment can be applied to the population and the real world






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






22. 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%






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






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






25. 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






26. Aims to match demographic characteristics to population (i.e. 50% female - etc)






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






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






29. 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%






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






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






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






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






34. 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






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






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






37. Used most commonly on standardized test






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






39. 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






40. 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






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






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






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






44. 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






45. Combines longitudinal and cross-sectional approach






46. Used when equivalent one cannot be isolated






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






48. Mean of Americans is standardized to 100 - with SD 15 or 16 depending on test; correlates most with IQ of biological parents and socioeconomic status






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






50. 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
