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. Numerically calculating and expressing correlation - r range -1 to +1 - 0 = no relationship






2. Process in testing concurrent validity






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






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






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






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






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






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






9. Used when equivalent one cannot be isolated






10. The hypothesis that no real differences or pattern exist






11. The most frequently occurring value






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






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






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






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






17. 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






18. 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






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






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






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






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






23. 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 -






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






25. Knowing how to do something






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






27. Whether test really taps abstract concept being measured






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






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






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






31. 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






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






33. Intelligence in relation to performance; pioneered development of psychometrics - 'no intelligence is culture-free'






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






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






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






37. Knowing a fact






38. For children 4-6






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






40. Similar to word association - finish incomplete sentences






41. 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






42. 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






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






44. 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






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






46. Attempts to eliminate/minimize these - variables in the environment that might also effect the dependent variable and blue the effect of independent variable on the dependent variable






47. Created multitrait-multimethod technique to determine validity of tests






48. Personality test from Jung'S theory; 93 questions 2 answers each; 4-letter personality type - each letter 1 of 2 possible opposing characteristics: Introverted vs. Extraverted - Sensing vs. Intuition - Feeling vs. Thinking - and - Judgment vs. Percep






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






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