If you assign your quiz to a class, students can login and download a pdf file with the graded quiz and view the results once you have released the results.
Select all the students in the grade view for which you want to release the results, choose "Release results" and then click "Apply". The lock in front of the result table will change from closed (black) to open (green).
Now when the student logs in and clicks on his quiz, he will see the results available for download.
If you released the results by mistake, you can choose the option "Lock/Hide results".
