1. Attempts to eliminate/minimize these - variables in the environment that might also effect the dependent variable and blue the effect of independent variable on the dependent variable






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






3. Used when n-cases in a sample are classified into categories or cells - tell us whether the groups are significantly different in size - look at the pattern or distributions - not difference between mean - ex:intro psych class categorized into race -






4. Overall range or spread - most basic measure of variability - subtracts the lowest value from the highest value in a data set






5. (Mental age/chronological age)/100 - Highest age = 16

6. Not intelligence tests; measure sensory and motor development of infants to identify mental retardation; poor predictors of later intelligence






7. 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






8. 31 cards (1 blank and 30 pictures) with interpersonal scenes (2 people facing each other); subject tells story about each which reveals aspects of personality; often measure need for achievement; interpreting terms include needs - press - personology






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






10. 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






11. Experimenter bias; researchers see what they want to see; minimized in double-blind






12. 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






13. 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






14. Draw a person of each sex and tell a story about them






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






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






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






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






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






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






21. When relationship inferred when there is none - ex: many people think there is a relationship between physical and personality characteristics - when evidence show there is none






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






23. Measures the extent to which items in a measure 'hang together' and test the same thing

25. Used most commonly on standardized test






26. Whether test really taps abstract concept being measured






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

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






30. The effect that might result when a group is born and raised in a particular time period






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






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






33. Whether test items look like they measure the construct






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






35. Takes place in controlled setting must be able to control for: independent variable - dependent variable - and confounding variable
