What is the median in the set of data 14 19 26 28 18 21 30 27?

To find the median, first, arrange the data in ascending order: 14, 18, 19, 21, 26, 27, 28, 30. Since there are 8 numbers (an even set), the median is the average of the two middle numbers, which are 21 and 26. Thus, the median is (21 + 26) / 2 = 23.5.
