Most of us know that the regression line minimizes the sum of squared residuals, but most of us don’t know how our calculators actually produce a slope and intercept for a regression line. This session will provide an answer to the question “How did my calculator do that?” It turns out that our calculators and other software use vectors to compute regression equations. We will look at the vector basis of regression; a certain level of comfort with vectors will be assumed.
This session will provide an overview of three categories of students' ways of thinking about basic combinatorics problems. Some of these approaches came naturally to students, while others required students to build upon previous techniques. We will discuss how to guide students to develop these new, often more sophisticated, approaches.

(3) Return your key (in the envelope provided) to the check out table in the Agora.
(4) Return any fans that were rented and receive your $10 deposit back. Drop fans in the Agora where you initially rented them.
(5) Bring your luggage to the Agora. We'll watch it until the buses are loaded.
General Conference Checkout
(1) Stop by the check out desk to pick up your check out folder.
(2) This folder contains your clock hour letter for your school and certificate of completion.
(3) If you did not stay on campus, plan to stop by the check out desk prior to 11:45 to pick up your packet.
