25% does not equal 0.11%

According to the Indiana Daily Student, "There were 22 sexual assaults reported on the (IU) campus in 2013." Assuming an enrollment of about 40,000 students, and assuming half of those students are women, that comes out to 0.11% of women on campus assaulted. So here's the question. The feminist line is 1 of 4 women in college are assaulted. Something does not add up, because 0.11% does not equal 25%.

On a related note, here is an article from Time.com arguing the "yes means yes" standard will "create a disturbing precedent for government regulation of consensual sex."
