Explanation:

In a box - and - whisker plot:

• The full range of the data is from the minimum to the maximum value (not just the left whisker).
• The range covered by the middle half of the data is the inter - quartile range (IQR), which is \(Q3 - Q1\) (related to the box part).
• The left whisker extends from the minimum value (which is the start of the first quarter of the data when the data is ordered). The first quarter of the data is from the minimum (\(Q0\)) to the first quartile (\(Q1\)).
