Five recovery times in days are 5, 6, 6, 7 and 30. Which value best describes a typical recovery time, and why?

  1. AThe mean of 10,8, because it uses every value
  2. BThe maximum of 30, because it shows the worst case
  3. CThe median of 6, because the outlier pulls the mean up
  4. DThe range of 25, because it shows the spread
