Data Surveys
on
Vila Health conducted a survey on the time patients had to wait in the emergency room (ER) before being seen by a triage nurse. The survey questions were mailed to patients after discharge. After receiving completed surveys from 100 patients, the researchers decided to delete several of the questions and only survey patients seen in the ER during the early morning hours. Discuss how changing the survey tool and restricting the data collection or sample time could compromise the research.
