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. Calculates how off the mean might be in either direction






2. 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






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






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






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






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






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






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






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






10. 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






11. 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






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






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






14. 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






15. Studying the same objects at different points in the lifespan and provides better - more valid results than most other methods - costly - time commitment






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






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






18. The process of representing or analyzing numerical data






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






20. Similar to word association - finish incomplete sentences






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






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






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






24. Knowing a fact






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






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






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






28. 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






29. 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






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






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






32. For children 6-16






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






34. Analyses how a large group responded to each item on the measure; weeds out problematic questions with low discriminatory value; increases internal consistency






35. 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






36. 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

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






39. Whether test really taps abstract concept being measured






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






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






42. 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
