  • If you are not ready to take this test, you can study here.

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

4. Normal curve - negatively skewed distribution - positively sknewed distribution - bimodal distribution - platykuric distribution






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






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






7. Whether test really taps abstract concept being measured






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






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






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






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






12. The most frequently occurring value






13. 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

16. Internal-External Locus of Control Scale

23. The process of representing or analyzing numerical data






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






25. 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






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






27. 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






28. When subjects act in ways they think experimenter wants or expects






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






30. Developed concept of IQ and first intelligence test (Binet Scale)






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






32. 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






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






34. 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






35. 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

37. Knowing a fact






38. Measure the extent to which test measures what it intends to; concurrent - construct - content - face
