The median is the middle value of a data set when the values are arranged in ascending or descending order.
First, let's arrange the data set in ascending order: 11, 11, 12, 12, 12, 15, 16, 17, 17
Since the data set has 9 values, the median will be the value in the middle.
In this case, the fifth value is 12.
Therefore, the median of the data set is 12.
Use this data set for all problems in this practice: 15, 12, 11, 16, 17, 12, 11, 17, 12
