The data show the number of free throws attempted by a team in its first ten games.
2, 11, 11, 11, 12, 12, 13, 14, 14, 15,
The median is 12 attempts and the mean is 11.5 attempts. After reviewing the data, it is determined that 2 should not be included, since that was an exhibition game rather than a regular game during the season.
What happens to the median if 2 attempts is removed from the data set?
