=Cats - Slope and Residual Tutorial=

Back to Scatterplots
 * This tutorial provides a conceptual approach to the analysis of bivariate data. **
 * 1) Create and analyze a scatterplot.
 * 2) Estimate a line of best fit (only if the pattern is linear).
 * 3) Estimate the slope (rate of change).
 * 4) Use residuals and the y_hat equation to predict values for the dependent variable.
 * 5) Identify an influential point (outlier).
