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






2. Whether test really taps abstract concept being measured






3. 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






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






5. Subjects alter behaviour because they are being observed






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






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






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

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






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






11. Like a histogram except that the vertical bars do not touch - various columns are separated by space






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






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






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






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






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






17. 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






18. 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






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






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






21. The hypothesis that no real differences or pattern exist






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






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






24. Similar to word association - finish incomplete sentences






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






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






27. Describe what is seen in each of 10 inkblots; scoring is complex; validity questionable






28. How the score are spread out overall






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






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






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






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






33. 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






34. Used most commonly on standardized test






35. 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






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






37. 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






38. 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






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






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






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






42. 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






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






44. Knowing how to do something






45. The process of representing or analyzing numerical data






46. 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






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






48. 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






49. 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






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