Researchers at an Australian university that introduced the use of plagiarism detection software in a number of courses surveyed 171 students enrolled in those courses (“Student and Staff Perceptions of the Effectiveness of Plagiarism Detection Software,” Australian Journal of Educational Technology [2008]: 222-240). In the survey, 58 of the 171 students indicated that they believed that the use of plagiarism- detection software unfairly targets students. Assuming it is reasonable to regard the sample as representative of students at this university, does the sample provide convincing evidence that more than one-third of the students at the university believe that the use of plagiarism-detection software unfairly targets students?
