Integrated Mathematics 2

Goal 3: Data Analysis and Probability - The learner will collect, organize, and interpret data to solve problems.

Objective 3.02. Create and use, for sets of data, calculator-generated models of linear, exponential, and quadratic functions to solve problems.

  • Interpret the constants, coefficients, and bases in the context of the data.
  • Check the model for goodness-of-fit and use the model, where appropriate, to draw conclusions or make predictions.

Learning to use R statistical software for linear regression — An alternative to the graphing calculator
In Understanding data mining: Extracting, organizing, and analyzing large sets of data, page 2
Students often learn how to do linear regression activities using a graphing calculator. This lesson provides an opportunity to complete these same types of assignments using R statistical software. Students will use this free software to create scatter plots and to develop linear regression models that can be used to make predictions.

Learning to use R statistical software for data mining — An extension of linear regression to multiple variables
In Understanding data mining: Extracting, organizing, and analyzing large sets of data, page 3
In this lesson, students will use the free R statistical software to navigate through the basics of data mining, a process in which the effects of individual variables can be determined. Students will utilize multiple methods of variable selection — forward selection, backward selection, and stepwise selection — in an attempt to determine which variables are most influential in a given situation.
