A new study by Ohio State University indicates college students who spend lots of time on social networking sites like Facebook have lower grades than peers who aren't Facebook users. Overall this observation isn't too shocking, it's pretty obvious that people who are addicted to Facebook have less time for studying.
The study's co-author, Ohio State University doctoral student Aryn Karpinski, evaluated 219 students who attend at OSU -- 117 graduates and 102 undergraduates -- during the summer and fall quarters last year. Of the 148 who admitted to using Facebook, their GPAs of 3.0 to 3.5 were lower than the 3.5 to 4.0 GPAs of non-Facebook users.
On average, Facebook users studied one to five hours per week, with non-Facebook users studying between 11 and 15 hours each week.
