I’ve created an excel workbook to help with calculations. I will be updating it as needed throughout the semester. It’s available in 3 formats: Click here to download xlsx (for Microsoft Excel). Click here to download ods (LibreOffice or OpenOffice). Click here to access the document on Google Drive. I’ve also created a program for the TI Calculator that will calculate the expected numbers for the \(\chi^2\) test for independence / homogeneity.
