As with any experiment, many opportunities for error existed on this one. The first noticeable mistake was in the questioning. Two important questions, gender and age, were neglected to be put on. This was a crucial mistake because males are naturally more violent than females and violence can wax or wane with age. There also exists the likelihood that a small amount of the students did not answer honestly or seriously. When the results were entered into the computer spreadsheet some of the answers could have put in the wrong column. But two people were used to enter the information very carefully thus lowering the chance of error. When testing a topic as broad as violent behavior a two page questionnaire obviously cannot address every possible factor. The small number of students tested also cannot represent an entire society.
