      10. Both lambda and Pearson's product moment correlation are based on guessing the mean. 11. Pearson's product moment correlation indicates how much of the variance in the dependent variable has been explained. 12. The general format for the regression line is y = a + b (X). The only observed quantity in this expression is X.

      Understanding the Pearson Correlation Coefficient (r) The Pearson product-moment correlation coefficient (r) assesses the degree that quantitative variables are linearly related in a sample. Each individual or case must have scores on two quantitative variables (i.e., continuous variables measured on the interval or ratio scales).
