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






2. The process of representing or analyzing numerical data






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






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






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






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






7. Consist of vertical bars in which the sides of the vertical bars touch - useful for discrete variables that have clear boundaries - interval variables in which there is some order






8. Internal-External Locus of Control Scale






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






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






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






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






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






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






15. Measure the extent to which test measures what it intends to; concurrent - construct - content - face






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






17. For children 4-6






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






19. 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






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






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






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






23. 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






24. Process in testing concurrent validity






25. 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






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






27. For children 6-16






28. Mean is 0 - and SD=1 - This with Z-score allow you to compare one person'S score on two different distributions






29. For even number of values in the set - take the average of the two middle value






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






31. Have order - equal intervals and a real zero ex: age






32. Data that has been counted rather than measured - usually limited to whole or positive values - ex: group size - number of hospital visit - number of symptoms






33. 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






34. Similar to word association - finish incomplete sentences






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






36. Experimenter bias; researchers see what they want to see; minimized in double-blind






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






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






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






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






41. 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






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






43. Compares 2 groups of people at the same time point






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






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






46. 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






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






48. 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






49. 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






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