Question

what is the range of the dataset represented by the boxplot if you ignore the outlier?

Explanation:

Step1: Recall the formula for range

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

Step2: Identify maximum and minimum values

From the box - plot (ignoring the outlier), the maximum value is \( 30 \) and the minimum value is \( 7.5 \).

Step3: Calculate the range

Substitute the values into the formula: \( \text{Range}=30 - 7.5=22.5 \).

Answer:

\( 22.5 \)
