Chi-Squared Data Analysis and Model Testing for BeginnersRecent groundbreaking discoveries in physics, including the discovery of the Higgs Boson and gravitational waves, have relied on chi squared analysis and model testing, a data analysis method. This is the first book to make chi squared model testing accessible to students in introductory physics lab courses and others who need to learn this method, such as beginning researchers in astrophysics and particle physics, beginners in data science, and lab
