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. Compares 2 groups of people at the same time point






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






3. 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%






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






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






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






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






8. When subject behave differently just because they thing that they have received the treatment substance or condition






9. 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






10. Internal-External Locus of Control Scale






11. Subjects alter behaviour because they are being observed






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






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






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






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






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






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






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






19. Similar to word association - finish incomplete sentences






20. 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






21. 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






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






23. Interest in the effect of independent variable on the dependent variable - often manipulated by applying it in experimental or treatment condition and withholding it from control condition






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






25. For children 6-16






26. Fluid intelligence declines with old age while crystallized intelligence does not






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






28. 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






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






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






31. Knowing how to do something






32. For children 4-6






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






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






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






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






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






38. Used when equivalent one cannot be isolated






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






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






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






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






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






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






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






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






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






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






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






50. 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%
