Final answer:
Studies showed that 9 percent of students according to the U.S. Department of Education and 17 percent according to the National Center for Educational Statistics reported being victims of cyberbullying. The Cyberbullying Research Center reported about 28 percent of teens experiencing cyberbullying.
Step-by-step explanation:
The percentage of parents that reported having a child who has been cyberbullied can be found through various studies and reports. The U.S. Department of Education's 2011 study reported that 9 percent of students aged twelve through eighteen specifically reported being victims of cyberbullying. Additionally, the report by the National Center for Educational Statistics in 2013 indicated that 17 percent of students reported being victims of cyberbullying.
Moreover, data from the Cyberbullying Research Center suggests that about 28 percent of teens have experienced cyberbullying. It is evident from these reports that cyberbullying is a significant issue among youth, and through initiatives like the Bullying Prevention summit hosted by the White House in 2011, awareness and preventive measures are being emphasized.
