カイ二乗分布【中学の数学からはじめる統計検定®２級講座第13回】

#Statistics #ChiSquareTest #GoodnessOfFitTest This video is for preparation for the Statistical Test® Level 2 exam, but it's also recommended for those planning to take the QC Test Level 2 exam or university students looking to understand statistics classes! The chi-square distribution can be a confusing concept. Starting with an explanation of the name "chi-square," I explain how to calculate probability and its graphical features, and then provide an easy-to-understand explanation of its applications, including population variance estimation and goodness-of-fit tests. *Statistical Test® is a registered trademark of the Statistical Quality Assurance Promotion Association. ▶︎Blog https://toketarou.com/chi_square/ If you have any questions about this video or the corresponding blog post, please leave them in the comments section and I'll answer them.
