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






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






3. 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






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






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






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






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






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






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






10. 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






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






12. The hypothesis that no real differences or pattern exist






13. 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






14. 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






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






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






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






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






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






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






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






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






23. Used most commonly on standardized test






24. 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






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






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






27. Knowing a fact






28. Not to diagnose depression but assess severity of depressive symptoms; used by researcher or clinician to track course of depressive symptoms






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






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






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






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






33. The process of representing or analyzing numerical data






34. 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






35. How the score are spread out overall






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






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

38. 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






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






40. For children 6-16






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






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






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






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






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






46. Combines longitudinal and cross-sectional approach






47. 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%






48. Whether test really taps abstract concept being measured






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






50. 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
