    In a box plot with Min = 5, Q1 = 12, Median = 18, Q3 = 28, Max = 35, what is the difference between Median and Q1?

  11. MultiChoice

    In the box plot (Min = 5, Q1 = 12, Median = 18, Q3 = 28, Max = 35), what is the difference between Max and Q3?

  12. MultiChoice

    Why is the IQR often preferred over the range when outliers are present?
