Big Ideas: Problems that exist within the real-world, including seemingly random bivariate data, can be modeled by various algebraic functions. This lesson builds on students’ prior work with quadratic modeling. This task focuses on the bivariate data from a study that estimated the number of AIDS cases each year for the past 10 years. This builds towards their understanding of how polynomials can be used in regression systems modeling that comes up later in Algebra 2 and in Advanced Placement and college level courses. Vocabulary: Bivariate Data, Model, Quadratic, Parabola, Regression, Coefficient of Determination Special Materials: Graphing Calculator or spreadsheet software for regression modeling.
