Question

find the range of the data set using the box plot.

Explanation:

Step1: Recall the formula for range

The range of a data set is calculated as \( \text{Range}=\text{Maximum value}-\text{Minimum value} \).

Step2: Identify maximum and minimum values from the box - plot

From the box - plot, the minimum value (left - most end of the whisker) is \( 50 \) and the maximum value (right - most end of the whisker) is \( 400 \).

Step3: Calculate the range

Substitute the values into the formula: \( \text{Range}=400 - 50\).

Answer:

\( 350 \)
