Question

the box plot below represents some data set. approximately what percentage of the data values are greater than 65?

Explanation:

Step1: Recall box - plot properties

In a box - plot, the median (the line inside the box) divides the data into two equal parts. Approximately 50% of the data lies above the median and 50% lies below the median.

Step2: Identify the median position

Looking at the box - plot, the median (the middle line of the box) is at 65. So, the data values greater than 65 will be the data values that are above the median.
Since the median divides the data set into two equal - sized groups (in terms of percentage), the percentage of data values greater than 65 is approximately 50%.

Answer:

50%
