My survey on books

I got five replies to my survey.
From my survey, I know that there are not so many students who read books on the Internet in this class. Also, many people think that reading have some good effect on our study. The kinds of books they like varied from person to person, but most people like novels or comics. How often they read books was quite different from person to person and there were nothing in common in the answers to this question.
That's what I found from my survey.
