Question

the box-and-whisker plot below represents some data set. what is the range of the data? box-and-whisker plot image with number line from 0 to 100, key marks at 0,20,40,60,80,100

Explanation:

Step1: Identify min and max values

From the box - and - whisker plot, the minimum value (left whisker end) is 30 and the maximum value (right whisker end) is 90.

Step2: Calculate the range

The formula for the range of a data set is \( \text{Range}=\text{Maximum value}-\text{Minimum value} \).
Substituting the values, we get \( \text{Range}=90 - 30=60 \).

Answer:

60
