Apologies for the confusion. Let's calculate the median of the original dataset: 2, 5, 19, 16, 12, 14, 4, 12, 8.
Arranging the data in order: 2, 4, 5, 8, 12, 12, 14, 16, 19.
Since there are 9 data points, the median is the middle value, which is 12 in this case.
If we remove one of the 12s from the dataset, the new dataset will be: 2, 5, 19, 16, 14, 4, 12, 8.
Arranging this new dataset in order: 2, 4, 5, 8, 12, 14, 16, 19.
In this case as well, the median is the middle value, which is now 12 after removing one of the 12s.
Therefore, the median stays the same even after removing 12 from the dataset.
