Parks planners survey only weekday downtown office visitors about weekend trail use and conclude citywide demand is low. What sampling problem should the information manager flag?
Select an answer to reveal the explanation.
Short Explanation
Asking weekday office folks about weekend trails is like polling only lunch-rush diners about midnight menu demand—you'll miss the people who actually show up later. The sampling frame left out evenings, weekends, and other neighborhoods. Fix who you ask before you trust the 'citywide' number.
Full Explanation
Sampling bias arises when the frame systematically excludes populations relevant to the decision. Weekend trail users differ from weekday downtown office visitors, so estimates of citywide parks usage will be skewed. Managers should redesign the frame to cover relevant times, places, and user groups.
