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. 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






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






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






4. Measure of fascism or authoritarian personality






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






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






7. Allows own answer: expression of conflicts - needs - impulses; content interpreted by administrator - some more objective than others; Rorschach Inkblot Test - Thematic Apperception Test - Rosenzweig Picture-Frustration (P-F) Study - Word Association






8. Mean is 0 - and SD=1 - This with Z-score allow you to compare one person'S score on two different distributions






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






10. Notable for cross-cultural application and simple directions - to make the best picture of a man - scored based on detail and accuracy - not artistic talent






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






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






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






14. Used most commonly on standardized test






15. Knowing how to do something






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






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






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






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






20. 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






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






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






23. The process of representing or analyzing numerical data






24. Whether test items look like they measure the construct






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






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






27. 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






28. For children 6-16






29. 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






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






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






32. Developed concept of IQ and first intelligence test (Binet Scale)






33. The approach to construct assessment instruments - involves selection of items that can discriminate between various groups; responses determine if he is like a particular group or not; e.g. Strong-Campbell Interest Inventory






34. Mean of Americans is standardized to 100 - with SD 15 or 16 depending on test; correlates most with IQ of biological parents and socioeconomic status






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






36. The hypothesis that no real differences or pattern exist






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






38. Created multitrait-multimethod technique to determine validity of tests






39. Combines longitudinal and cross-sectional approach






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






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






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






44. 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






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






46. 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






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






48. 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






49. Internal-External Locus of Control Scale






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