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. Revised Binet scale to Stanford-Binet Intelligence Scale; also studied gifted children - those with higher IQs better adjusted






2. Knowing a fact






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






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






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






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






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






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






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






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






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






12. Tell you the average extent to which scores were different from the mean - if average standard deviation is large - then scores were highly dispersed






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






14. Draw a person of each sex and tell a story about them






15. Might show how often different variables appear; nominal - ordinal - interval - ratio (real zero)






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






17. Not intelligence tests; measure sensory and motor development of infants to identify mental retardation; poor predictors of later intelligence






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






19. For children 4-6






20. 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 -






21. Measure of fascism or authoritarian personality






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






23. 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






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






25. 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%






26. 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






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






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






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






30. 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%






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






32. The process of representing or analyzing numerical data






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






34. 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






35. 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






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






37. Tests the same person at multiple time points and looks at changes within that person






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






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






40. Mathematically combines and summarizes overall effects or findings for a topic; best known for consolidating effectiveness of psychotherapy - can calculate overall effect size or conclusion drawn from a collection of studies; needed when conflicting






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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






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






44. Measure mastery in a particular area (e.g. final exam)






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






46. 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






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






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






49. When relationship inferred when there is none - ex: many people think there is a relationship between physical and personality characteristics - when evidence show there is none






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