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






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






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






4. 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%






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






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






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






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






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






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






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






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






13. Numerically calculating and expressing correlation - r range -1 to +1 - 0 = no relationship






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






15. The most frequently occurring value






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






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






18. Combines longitudinal and cross-sectional approach






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






20. Knowing how to do something






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






22. Originally to determine mental illness - now for personality; more clinical than CPI; 550 T/F/unsure questions (e.g. 'I would like to ride a horse'); discriminates between disorders; high validity because highly discriminatory items and 3 validity sc






23. 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%






24. Knowing a fact






25. 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






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

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






28. Whether test items look like they measure the construct






29. 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






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






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






32. 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






33. How the score are spread out overall






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






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






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






37. 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






38. 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






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






40. 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






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






42. 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






43. Measure how well you know a subject - measure past learning






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






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






46. Attempt to measure less-defined properties (e.g. intelligence) - check for reliability and validity






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






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






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






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