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. 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






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






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






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






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






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






8. 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






9. Used most commonly on standardized test






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






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






12. The hypothesis that no real differences or pattern exist






13. Tests whether at least 2 groups co-vary - can adjust for preexisting differences between groups






14. 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%






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






16. Knowing how to do something






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






18. Measure of fascism or authoritarian personality






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






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






21. Whether test items look like they measure the construct






22. For children 6-16






23. 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






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






25. 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 -






26. Measure innate ability to learn (debatable) - to predict later performance






27. 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






28. 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






29. 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






30. Internal-External Locus of Control Scale






31. Notable for cross-cultural application and simple directions - to make the best picture of a man - scored based on detail and accuracy - not artistic talent






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






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






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






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






36. 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






37. Neither the subject nor the experimenter know whether the subject is assigned to the treatment or the control group






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






39. The process of representing or analyzing numerical data






40. 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






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






42. 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






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






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






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






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






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






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






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






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