Google Sheets: Performing a Chi-Squared Test HD

This video explains how to perform a Chi-Squared test of independence on a two-way table using Google Sheets. The techniques will also work on other spreadsheets. The intended audience is IBDP mathematics students, particularly those taking the Mathematical Studies course or the new "Applications & Interpretation" course from 2019. The video shows how to calculate the test statistic without using the built-in functions.
