Question

the box - and - whisker plots show data on the heights, in meters, of all waves measured at an ocean beach on two separate days. what is the difference of the median wave height from day 1 and the median wave height from day 2, in meters?

Explanation:

Step1: Identify median of Day 1

The median of Day 1 is at 1.4 meters (the line inside the box - and - whisker plot for Day 1).

Step2: Identify median of Day 2

The median of Day 2 is at 1.8 meters (the line inside the box - and - whisker plot for Day 2).

Step3: Calculate the difference

Subtract the median of Day 1 from the median of Day 2: $1.8 - 1.4$.
$1.8-1.4 = 0.4$

Answer:

0.4
