A number of patients who received pacemakers at a hospital have complained that instead of feeling better, they feel worse. They have low energy and find themselves needing to rest for long periods of time after completing only a small task. Upon looking into this further, it is discovered that the patients’ doctor has completely failed to adjust the settings according to patient needs. Instead, he simply gave each patient a pacemaker with the factory settings. Once the pacemakers have been adjusted to fit individual patient requirements, patients returned to say that they have been feeling great and have more energy than ever. Which of the following best describes this type of statistical variation among patients?
