This portfolio will demonstrate your
understanding of our study of statistics and how statistics influence the world
around us. Each step should be done
completely and checked by your teacher before you move to the next step. Take your time, be thorough and have
fun. Be sure to show your work on all
calculations.
Failure to submit checkpoint on or before
due date will result in a 1-point deduction for that step.
