The value "9" is the median of the dataset, which means it is the middle value when the numbers are arranged in ascending order. Since there are 9 numbers, the median is the 5th number, which corresponds to the 50th percentile. This is also represented by the formula for finding the median position in an ordered list, which is (N+1)/2, where N is the number of observations in the dataset.
