Activity Overview

In this lesson, students will calculate the volume of blood in their own bodies based on a linear regression.


  • Students will calculate the volume of blood in their own bodies.
  • Students will analyze and quantify some of the components of their blood.
  • Students will use tabular data to accurately generate a scatter plot.
  • Students will generate a linear regression model, use the function to perform calculations, and interpolate a value on the regression model.


  • plasma
  • erythrocytes
  • leukocytes
  • milligram
  • microliter

About the Lesson

This lesson involves generating a linear regression model for human blood volume vs. body weight.
As a result, students will:

  • Algebraically calculate their own blood volume.
  • Interpolate on the regression model to determine their blood volume.
