A district administrator wants to determine the effect of truancy on academic achievement. She asks the dean at a high school to randomly select the records of 50 truant students and to randomly select the records of 50 nontruant students.  Identify any problems that are likely to cause confounding.
◦ nothing (this is a well-designed retrospective study)
◦ the number of records in each group (since, presumably, there are more nontruant students, there should be more members selected from that group)
◦ the use of records from only one school
◦ the use of one person to select the records for members of both groups
