Students use their equation to calculate the profit based upon various advertising budgets and vice versa. Finally, students learn the definition of the regression line of best fit and how to compute it using Desmos. Student knowledge of linear equations in slope-intercept form is assumed.
Linear regression is a fundamental tool for understanding and predicting relationships between variables. Through this activity, we will demystify the concept of linear regression and showcase how the least squares method plays a crucial role in finding the line of best fit.
Students will determine if a data set is best represented by a linear or a quadratic model, write the equation of best fit for a data set using linear or quadratic regression, and make predictions using the equation of best fit.
