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






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






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






4. 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






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






6. Empirical-keying or criterion-keying approach; to determine of subject is like a particular group or not






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






8. 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






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






10. 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






11. 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%






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






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






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






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






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

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






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






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






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






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






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






23. 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






24. Whether content covers a good sample of construct being measured






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






26. 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






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






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






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






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






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






32. Knowing a fact






33. 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






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






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






36. 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






37. How the score are spread out overall






38. Measured by the same individual taking the same test more than once






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






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






41. Measure the extent to which test measures what it intends to; concurrent - construct - content - face






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






43. Takes place in controlled setting must be able to control for: independent variable - dependent variable - and confounding variable






44. Draw a person of each sex and tell a story about them






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






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






47. Used most commonly on standardized test






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






49. Consist of vertical bars in which the sides of the vertical bars touch - useful for discrete variables that have clear boundaries - interval variables in which there is some order






50. Similar to word association - finish incomplete sentences
