In a recent survey of students who graduated from a large public high school, nine out of ten students reported that they passed biology with a grade of seventy-five percent or higher. What further data could be produced to be sure that this information is accurate?

To check whether students accurately reported their biology grades, compare their answers with an independent, official record. Reviewing the students’ school transcripts would show whether they earned at least 75% in biology. Surveys, parent consultations, or interviews with a different graduating class would not directly verify these students’ grades.
