In a survey of all 14,000 undergraduates in a University, over the last four years, an average of 61 percent admitted to cheating on assignments and examinations. The figure declined somewhat from 65 percent earlier in the decade, but the number students cheating in examinations as reported by the examination office has increased over the same period.
Which of the following best explains the discrepancy outlined above?
A.) The examinations office has become more effective in identifying instances of cheating.
B.) Those students who used to earlier cheat in assignments have now started cheating in examinations alone.
C.) The number of students who cheat has increased but the percentage has decreased over the past 4 years.
D.) Students have not provided correct and representative answers in the survey and thus impacted the validity of the results.
E.) The sample of 14,000 students is not large enough to draw such inferences about the whole University.
