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






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






3. 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%






4. 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






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






6. 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






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






8. 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






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






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






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






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






13. 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






14. 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






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






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






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






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






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






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






21. 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






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






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






24. Measure of fascism or authoritarian personality






25. Measures the extent to which items in a measure 'hang together' and test the same thing






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






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






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






29. Used when equivalent one cannot be isolated






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






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






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






33. 31 cards (1 blank and 30 pictures) with interpersonal scenes (2 people facing each other); subject tells story about each which reveals aspects of personality; often measure need for achievement; interpreting terms include needs - press - personology






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






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






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






37. Similar to word association - finish incomplete sentences






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






39. 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






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






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






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






43. 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






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






45. When subjects act in ways they think experimenter wants or expects






46. 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






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






48. Internal-External Locus of Control Scale






49. Originally used with free association techniques; word called out - subject says next word in mind






50. Whether test really taps abstract concept being measured
