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. 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






2. 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






3. 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






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






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






6. For ranks; determining the line that describes a linear relationship






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






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






9. 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






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






11. Capable of showing order and pacing because equal spaces lie between the values - do not include real zero - ex: temperature






12. 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






13. 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






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






15. The process of representing or analyzing numerical data

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






19. 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






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






21. Whether test really taps abstract concept being measured






22. Knowing how to do something






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






24. Tests whether the means on one outcome or dependent variable are significantly different across groups - height or level of anxiety from anxiety scale






25. 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






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






27. Internal-External Locus of Control Scale






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






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






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






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






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






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






34. 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






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






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






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






38. 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






39. Used most commonly on standardized test






40. Knowing a fact






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






42. The most frequently occurring value






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






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






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






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






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






48. 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






49. Measure of fascism or authoritarian personality






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