To find the range of the data represented in a box and whiskers plot, you need to identify the minimum and maximum values. The range can be calculated using the formula:
\[ \text{Range} = \text{Maximum} - \text{Minimum} \]
From the values given: 20, 46, 58, and 66, we have:
- Minimum = 20
- Maximum = 66
Now, substitute these values into the formula:
\[ \text{Range} = 66 - 20 = 46 \]
Thus, the range of the data is 46.
