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. Similar to word association - finish incomplete sentences






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






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






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






5. Whether test really taps abstract concept being measured






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






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






8. Internal-External Locus of Control Scale






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






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






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






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






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






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






15. Used when equivalent one cannot be isolated






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






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






18. The hypothesis that no real differences or pattern exist






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






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






21. Measure the extent to which test measures what it intends to; concurrent - construct - content - face






22. Process in testing concurrent validity






23. Organize data by showing it in a meaningful way; do not allow conclusions to be drawn beyond the sample; percentiles - frequency distributions - graphs - measures of central tendency - variability






24. Sorting cards into a normal distribution; each has a different statement on it about personality; to one end is 'least like self' - other is 'most like self' - and middle is neutral; factor analysis to reduce viewpoints into a few factors






25. 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%






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






27. Fluid intelligence declines with old age while crystallized intelligence does not






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






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






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






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






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






33. How stable measure is; test-retest - split-half






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






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






36. Knowing how to do something






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






38. 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






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






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






41. Tell you the average extent to which scores were different from the mean - if average standard deviation is large - then scores were highly dispersed






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






43. The most frequently occurring value






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






45. 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






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






47. 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






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






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






50. Neither the subject nor the experimenter know whether the subject is assigned to the treatment or the control group
