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






2. 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






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






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






5. 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






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






7. Internal-External Locus of Control Scale






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






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






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

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






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






13. For children 4-6






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






15. 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






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






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






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






19. Subjects alter behaviour because they are being observed






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






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






22. Has plotted points connected by lines - used to plot variables that are continuous (categories without clear boundaries)






23. 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






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






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






26. Allow generalization from sample to population - statistics (sample) - parameters (population): use statistics to estimate parameters






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






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






29. 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






30. 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






31. How the score are spread out overall






32. 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






33. 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






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






35. 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






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






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






38. 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






39. 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%






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






41. If it is significant - same finding can be generalized to the population - use test of significant to reject null hypothesis






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






43. 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






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






45. 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






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






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






48. There is a general factor in intelligence 'g'






49. 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






50. Comparing an individual'S performance on 2 halves of the same test to reveal internal consistency; internal consistency can be increased by item analysis
