Quizplus · Accepted Answer

The median is the middle value of a data set that has been arranged in order of magnitude. For the given data set (12, 32, 48, 8, 22, 9, 30, and 18), when arranged in ascending order, it becomes 8, 9, 12, 18, 22, 30, 32, and 48. Since there are an even number of data points, the median is the average of the middle two values, which are 18 and 22. Thus, the median = (18 + 22) / 2 = 40 / 2 = 20.
