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. Interest in the effect of independent variable on the dependent variable - often manipulated by applying it in experimental or treatment condition and withholding it from control condition






2. Knowing how to do something






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






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






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






6. 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






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






8. Bell curve; larger the sample - greater chance of having a normal distribution






9. The hypothesis that no real differences or pattern exist






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






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






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






13. 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






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






15. 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






16. 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






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






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






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






20. 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%






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






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






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






25. Similar to word association - finish incomplete sentences






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






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






28. Measure innate ability to learn (debatable) - to predict later performance






29. 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






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






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






32. For ranks; determining the line that describes a linear relationship






33. Used when n-cases in a sample are classified into categories or cells - tell us whether the groups are significantly different in size - look at the pattern or distributions - not difference between mean - ex:intro psych class categorized into race -






34. 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






35. Frequency polygon (continuous variables) - histogram/ bar graph (discrete)






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






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






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






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






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






41. 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

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






46. The most frequently occurring value






47. Used when an experiment involves more than one independent variable - can separate the effects of different levels of different variables - can isolate main effects - can identify interaction effects - ex: studying effect of brain lesion on problem s






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






49. Combines longitudinal and cross-sectional approach






50. Compares 2 groups of people at the same time point
