This document contains the notes from a statistics lesson. It includes instructions for students to listen carefully, work individually, and raise their hand for questions. The lesson will cover summarizing bivariate categorical data using frequency tables and relative frequency tables. Students are reminded of classroom behavior expectations and homework policies. Exercises from the statistics package and Khan Academy skills will be used to reinforce the concepts.
