Here is a brief collection of activities my students have done in AP Statistics.


  • 1. Least Squares
  • 2. Sum of residuals gives line of best fit?
  • 3. How many tanks?
  • 4. Binomial approximation
  • 5. Probability distribution of dice
  • 6. Baseball

Least Squares

Slide to the next stage, then move the blue points around the perimeter to find the line of best fit for the points shown. [br]Then keep advancing stages to see how well you do.[br]Click the button for a new set of points.
The object is to estimate the 'least squares' line. [br]Stage 1 shows you the points.[br]Stage 2 gives you the opportunity to estimate the line of best fit. [br]Stage 3 plots the residuals.[br]Stage 4 give you the 'square' of the residuals. [br]Stage 5 reveals the true least squares regression line.
