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. 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






2. The hypothesis that no real differences or pattern exist






3. Assess extent interests and strengths match those found by professionals in a particular job field






4. Used when an experiment involves more than one independent variable - can separate the effects of different levels of different variables - can isolate main effects - can identify interaction effects - ex: studying effect of brain lesion on problem s






5. 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






6. Used when equivalent one cannot be isolated






7. 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






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






9. Knowing a fact






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






11. Similar to word association - finish incomplete sentences






12. 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






13. Subjects alter behaviour because they are being observed






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






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






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






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






18. Whether test really taps abstract concept being measured






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






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






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






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






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






24. 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






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

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






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






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






29. 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






30. Birth order vs. intelligence; the older - the more intelligent; the more children - the less intelligent; the greater spacing - the more intelligent






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






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






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






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






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






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






37. How the score are spread out overall






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






39. 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






40. 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






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






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






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






44. Internal-External Locus of Control Scale






45. Includes: testable hypothesis - reproducible experiment - operationalized definition (observable and measurable)






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






47. 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%






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






49. Used when n-cases in a sample are classified into categories or cells - tell us whether the groups are significantly different in size - look at the pattern or distributions - not difference between mean - ex:intro psych class categorized into race -






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