A dataset contains the values: 8, 12, 14, 15, 17, 18, 20, 22, 250. The mean is approximately 63.9. A researcher calculates the 10% trimmed mean by removing one value from each tail (removing 8 and 250), yielding a trimmed mean of approximately 16.1. Why is the trimmed mean substantially different from the original mean?
