Understanding Confusion Matrices for Logistic Regression in Google Sheets

Understanding the performance of a classification model is crucial in data science. We typically use logistic regression when the outcome or response variable is binary (e.g., Yes/No, 0/1, Success/Failure). Evaluating how well this model predicts outcomes requires robust statistical tools. One of the most essential tools for assessing classification quality is the confusion matrix. This
