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.

2. Whether test really taps abstract concept being measured

3. 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

4. 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

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

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

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

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

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

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

21. Use correlation coefficients in order to predict one variable y from another variable x - let you define a line on graph that describes the relationship between x and y - when the least-square line or regression line is fit to the data - basically: u

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

23. 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

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

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

26. Subjects alter behaviour because they are being observed

27. 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

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

29. Birth order vs. intelligence; the older - the more intelligent; the more children - the less intelligent; the greater spacing - the more intelligent

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

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

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

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. 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

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