**Exam 3 Topics** (Chapters 9-11) [Multiple choice topics] proportion of variability explained, unexplained coefficients of determination (r^2^) and nondetermination (k^2^) standard error of the estimate, variance of the estimate variance of the estimate and correlation correlations: direction and magnitude covariance least squares regression line characteristics of a regression line correlation and prediction what does Pearson r measure truncated range bivariate outlier increasing/decreasing r homoscedasticity advantage and/or disadvantage of matched t test correlation and matched t when to use a repeated measures or matched pairs design advantage and/or disadvantage of repeated measures or matched pairs design order effects, carry over effects counterbalancing different designs: for example: simultaneous measurement, successive measurement (including before-after) [Computation] 1. One correlation: r, hypothesis, test for significance, interpretation of results 2. One regression: slope, intercept, equation, coefficients of determination and nondetermination (and interpretation of them), variance of the estimate (and interpretation), if given X, what would you predict Y to be? 3. Reading SPSS output: slope, intercept, correlation from regression output 4. One matched-t question: what type of design, hypotheses (symbols and words), standard error of the difference scores, t-test, df, cv, reject or not, interpretation Always know how to write up results in APA format.
