Quiz 3.1

Objectives

  •  Interpret the slope and y intercept of a least-squares regression line.

  • Use the least-squares regression line to predict y for a given x. Explain the dangers of extrapolation.

  • Calculate and interpret residuals.

  • Explain the concept of least squares.

  • Determine the equation of a least-squares regression line using technology or computer output.

  • Construct and interpret residual plots to assess whether a linear model is appropriate.

  • Interpret the standard deviation of the residuals and r^2 and use these values to assess how well the least-squares regression line models the relationship between two variables.

  • Describe how the slope, y intercept, standard deviation of the residuals, and r^2 are influenced by outliers.

  • Find the slope and y intercept of the least-squares regression line from the means and standard deviations of x and y and their correlation.

Agenda
