A survey of students at an elite private university found that 95% of them felt well-prepared for their careers. From this, the researchers concluded that universities in general are successfully preparing students for the workforce.

What is the flaw in the researchers' reasoning?

  1. The argument assumes that career preparation is the single most important goal a university has.
  2. The survey relied on student self-reporting of readiness rather than on direct employer feedback.
  3. The researchers chose to report their key finding as a percentage instead of using the raw counts.
  4. A self-reported figure as high as 95% is statistically implausible and was therefore most likely fabricated.
  5. Students at one elite private university are not a representative sample of all university students.
