This Canvas Guide introduces you to the quiz statistics available for Classic Quizzes (not New Quizzes). This includes an overall quiz summary e.g. average score, average time to complete etc. plus a breakdown of each question. The breakdown shows the percentage of students that chose each answer along with the names of the students. Quiz statistics can be filtered on section if you have multiple sections of students on your course. As well as these quiz statistics the resource shows you how to download an analysis of individual student performance (Student Analysis) and of the effectiveness of each multiple choice and true/false question (Item Analysis). This is a relatively comprehensive guide.
