The range of a data set is the difference between the largest and smallest values. Given the range is 12 and the largest value is 25, the smallest value must be 25 - 12 = 13. The median of a data set with only two values is the average of those two values. Therefore, the median is (25 + 13) / 2 = 38 / 2 = 19.
