1. 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






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






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






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






5. Population --> sample/subgroup --> representative and unbiased --> achieved through random sampling --> if it'S not feasible - use convenience sampling instead or stratified sampling






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






7. 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






8. Process in testing concurrent validity






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






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






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






12. 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






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






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






15. Compares 2 groups of people like an experiment - but this is used when it is not feasible or ethical to use random assignment ex: smoker vs. cancer






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






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






18. Whether test really taps abstract concept being measured






19. How well a test measures a construct; multitrait-multimethod technique determines validity; internal - external: concurrent - construct - content - face






20. The degree to which the result from an experiment can be applied to the population and the real world






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






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






23. For children 4-6






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






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






26. 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






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

29. 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






30. 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






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






32. 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






33. 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






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






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






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






37. 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

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






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






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