Survey Result -Teenage Suicide

Our group, A Hyun, Asuka and me, surveyed about Teenage Suicide. This is because The rate of teenage suicide in the U.S. is so high and I wondered what they think of it.
Our survey was held at Student Center, Faner Hall and Neely Hall where we live in on February 25th.
Our subjects are 30 people(male: 14/female: 16). We have surveyed 10 people each person.

There are two hypothesises I think; One is Americans are worried about Teenage suicide because its rate is very high. The other is they feel stress about friends relationship and academic pressure.
The Result tells us that almost half of them has experience that their acquaintance commited suicide, they feel stress about friends, academic pressure and loneliness, and the a half of them does not believe the teenage suicide will decrease.
The most interesting, I think, is a half of them thinks that teenage suicide will decrease. I have no idea why they answered like that because there is no efficient method to solve it. However, this will be the wish Americans have.
