Large sets of data, accessible through new technology, are paramount to forecasting trends in business and economics. In Algebra I, students typically study data sets with one predictor variable and one response variable. But in the real world, most response variables have numerous predictors which may significantly impact the data. It is important to be able to identify their effects and use them appropriately to make sound, valid predictions.
As a result of this project, mathematics students in grades nine through twelve will be able to extract useful information from large sets of data that represent multiple disciplines. Using these real-world applications, students will analyze data and use their findings to make predictions and to provide solutions to problems.
These lessons have been designed to help Algebra I students navigate the basics of data mining, and then learn to determine which variables are most influential in a given situation. Students will also use R© Statistical Software to help with variable selection.
