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).

Here is an interesting CODAP document. Note that the line drawn through the means of the two attributes intersects the LSR line.
