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 linear regression modeling. This task focuses on the bivariate data from a study that students conducted to see the relationship between the time a student studies and the grade they make on their test. This builds towards their understanding of how polynomials can be used in regression modeling of real-world bivariate data that comes up later in Algebra 2 and in Advanced Placement and college-level courses. Vocabulary: Bivariate, Linear, Regression, Model, Correlation Coefficient, Coefficient of Determination, Interpolate, Extrapolate Special Materials: Graphing Calculator or spreadsheet software for regression modeling.
