Classroom/Laboratory Activity: Linear Regression on Arctic Ice Data

A classroom/laboratory activity to perform linear regression on climate data from the Arctic.

Students will perform linear regression analysis on the average monthly extent of Arctic sea ice (from 1979 to the present) and will compare the residual plots for different months.

Use this tool to help your students find answers to:

  1. Create and compare the residual plots for the Arctic ice extent in March and September.
  2. Explain the difference observed in the two plots (Ref: 1.).
