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. Not simple and linear - looks like a curved line - ex: arousal and perfomance - high A --> low P - Low A --> low P - medium A --> high P






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






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






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






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






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






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






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






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






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






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






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






13. 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






14. 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%






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






16. 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






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






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






19. Similar to word association - finish incomplete sentences






20. The most frequently occurring value






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






22. 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






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






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






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






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






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






28. 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






29. How the score are spread out overall






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






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






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






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






34. 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






35. For children 6-16






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






37. Combines longitudinal and cross-sectional approach






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






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






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






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






42. 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






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






44. If it is significant - same finding can be generalized to the population - use test of significant to reject null hypothesis






45. For children 4-6






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






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






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






49. Tests the same person at multiple time points and looks at changes within that person






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