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






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






3. I when incorrectly reject null - thought significant but chance; II when incorrectly accept null - thought chance but significant






4. 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






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






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






7. Whether content covers a good sample of construct being measured






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






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






10. Whether scores on a new measure correlate with other measures known to test the same construct; cross validation process






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






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






13. 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






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






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






16. 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






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






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






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






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. (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


22. Whether test items look like they measure the construct






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






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






26. 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






27. 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






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






29. Describe what is seen in each of 10 inkblots; scoring is complex; validity questionable






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






31. 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






32. The most frequently occurring value






33. 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






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






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






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






37. Sorting cards into a normal distribution; each has a different statement on it about personality; to one end is 'least like self' - other is 'most like self' - and middle is neutral; factor analysis to reduce viewpoints into a few factors






38. Every member of the population has an equal chance of being chosen for the sample






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. 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 -






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






42. The hypothesis that no real differences or pattern exist






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






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






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






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






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






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






49. 31 cards (1 blank and 30 pictures) with interpersonal scenes (2 people facing each other); subject tells story about each which reveals aspects of personality; often measure need for achievement; interpreting terms include needs - press - personology
