  1. How do we measure variability for the marginal distribution
    • Use the SStotal 
    • Compute the SSerror
    • Contrast with a 1 way ANOVA
  2. How can we find the SSerror?
    Square and sum the residuals
  3. How can we find the SSregression?
    SStotal-SSerror

    This is the sum of squares of the predicted values
  4. How would we find the R2 value for regression analysis?
    SSregression divided by SStotal
  5. What is the null hypothesis tested by regression analysis?
    H0: b*(slope)=0
  6. What is the alternate hypothesis tested by regression analysis?
    • HA: b*≠0 (2 sided)
    • HA: b*>0 (1 sided)
