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. 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






3. The most frequently occurring value






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






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






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






7. Measured by the same individual taking the same test more than once






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






9. Subjects alter behaviour because they are being observed






10. 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






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






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






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






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






15. 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






16. How the score are spread out overall






17. The process of representing or analyzing numerical data






18. The age level of a person'S functioning according to the IQ test






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






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






21. 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






22. 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






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






24. Internal-External Locus of Control Scale

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






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






30. Mean of Americans is standardized to 100 - with SD 15 or 16 depending on test; correlates most with IQ of biological parents and socioeconomic status






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






32. 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






33. For children 6-16






34. 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






35. Assess extent interests and strengths match those found by professionals in a particular job field






36. 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






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






38. Process in testing concurrent validity






39. 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






40. Number of SD a score is from the mean - For normal distribution - (-3 to +3)






41. Knowing a fact






42. Used when an experiment involves more than one independent variable - can separate the effects of different levels of different variables - can isolate main effects - can identify interaction effects - ex: studying effect of brain lesion on problem s






43. 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






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






45. Measure arousal of sympathetic nervous system - stimulated by lying and anxiety
