How many students go to USU? 9 rapes reported in the last 3 years? One of eight will be raped while attending that school?
From those statistics (let's say that only 1/20 of the rapes are reported, just to make the numbers somewhat real). Let's also say they attend on average 4 years.
60 rapes each year (3 per year * 20).
240 rapes over 4 years.
1 in 8 female students raped during their stay at USU.
Therefore there must be about 2000 female students at USU.
Therefore there must be about 4000 students total.
I just looked it up. It says USU has 23,000 students (http://www.usu.edu/about/). Let's say that 14,000 are full-timers (it says that 10,000 are not on the main campus).
So it looks like, in reality, only about 1 in 65 rapes are reported.

"In a study of 6,000 students at 32 colleges in the US, 42% of rape victims told no-one and only 5% reported it to the police. (Warshaw 1994)"
In a survey of college males who committed rape, 84% said what they did was definitely not rape. (Warshaw, Robin 1994 "I Never Called It Rape")
After looking through the stats I think that each statistic should include how the survey defined rape. It seems there is a great degree of difference between some definitions than others. In some cases all it takes to qualify a rape is some hesitance (whether known to the rapist or not) on the part of the victim. In my personal opinion I don't think that is deserving of the stigma associated with rape.
In some cases I think the definition needs to be used less generally. I don't think that is a good thing to start to make people connect any type of assertiveness with rape.
