Description

Teach students how to calculate and interpret the Chi-Squared (χ²) statistical test with this clear, step-by-step lesson designed for AICE Marine Science and other high school biology or environmental science courses.

This resource helps students understand how scientists determine whether differences in data are due to chance or represent a real biological pattern.

The lesson walks students through the entire process—from stating the null hypothesis to interpreting statistical significance—using marine science examples that mirror the type of data analysis expected on Cambridge exams.

What’s Included:

• Teacher Presentation (14 Slides) – A ready-to-use PowerPoint lesson that guides students step-by-step through the Chi-Squared test.
• Student Handout & Practice Questions (4 Pages) – Students practice the full Chi-Squared process using marine ecology data.

Perfect For

• AICE Marine Science
• Marine Biology
• Environmental Science
• AP / IB Biology data analysis practice
• Lessons on scientific statistical tests
