Required & Recommended materials are listed below. I will invite students to their classroom via Haslett email prior to their first day of class. If you do not receive an invitation prior to the day of your first meeting with me, please send me an email at keathlkl@haslett.k12.mi.us.

  • A note about Calculators:

    AP Statistics is the only AP course for which a calculator is required. I will be using the two calculators shown here in demonstrations. If you do not already have a calculator, I highly recommend the TI-nspire CX. Please note that a TI-83 is not sufficient for this course. If you have questions about calculators, please feel free to email me.

    TI-84 Plus CE
    TI-nspire CX (or CAS)
