After students take the quiz, responses display in the "Responses" section of your editable form.
Summary Insights can tell you at a glance the average, median, range, point distribution, and frequently missed questions.
Question can tell you how many students (and which ones) selected each of your multiple choice options.
Individual will show you each student's quiz results one at a time. This is also where you would go to review responses individually before releasing scores, if you were scoring any sections manually.
