Goal 3

Data Analysis and Probability - The learner will collect, organize, and interpret data with matrices and linear models to solve problems.

Objective 3.03

Create linear models for sets of data to solve problems.

  • Interpret constants and coefficients 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.

Data Gathering - Linear Regressions
In groups of three, students gather data by experiment or observation in one of nine activities. Each group models the data they gathered, creates a display, and presents results to the class using an overhead projector.

Homerun Hoopla
This lesson is designed for students to gather and analyze data about baseball figures. The student will use the Internet or other resources to collect statistical data on the top five home run hitters for the current season as well as their career home run totals. The students will graph the data and determine if it is linear or non-linear.
