In order to find the median we need to organize the data set from smallest to greatest
[tex]7-9-10-12-15-16-16[/tex]then the median will be exactly the data in the middle, since the data set is not an even number it will be the forth number since the formula is
[tex]\vec{x}=x(\frac{n+2}{2})[/tex]then the median is 12.
