Question

What percent of the data is greater than the median?A box-and-whisker plot. The number line goes from 0 to 20. The whiskers range from 2 to 19 and the box ranges from 6.5 to 18. A line divides the box at 17.a.20%c.50%b.25%d.80%

Answer 1

`b.25\%`

1) Consider that the 1st Quartile corresponds to 25%, the Median is equivalent to 50% of the data, the Third Quartile to 75% of the data as the sketch below:

Notice that the Median is that bar inside the box, also known as the 2nd Quartile.

2) So the percentage of the data greater than the median is:

`75\%-50\%=25\%`
