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






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






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






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






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






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






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






8. 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






9. 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






10. 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






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






12. Personality measure for 'normal' / less clinical groups than MMPI - by Harrison Gough






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






14. 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






15. For children 6-16






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






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






18. Knowing how to do something






19. 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






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






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






22. 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






23. How the score are spread out overall






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






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






26. The most frequently occurring value






27. Most commonly used for adults 16+ - organized by subtests with subscales and identify problem areas; current is WAIS-IV






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. Combines longitudinal and cross-sectional approach






30. Similar to word association - finish incomplete sentences






31. Knowing a fact






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






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






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






35. The process of representing or analyzing numerical data






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






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






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






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






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






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






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






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






44. How a researcher attempts to examine a hypothesis - different questions call for different approaches - some approaches are more scientific than others






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






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






47. Describe what is seen in each of 10 inkblots; scoring is complex; validity questionable






48. Measure of fascism or authoritarian personality






49. compares means of 2 different groups to see if the two groups are truly different - analyze differences between means on continuous data - particularly useful with small n - cannot test for difference between more than 2 groups






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