When you put the earthworm farmers' salaries in numerical order to find the mean ($10,000, $18,000, $18,000, $19,000, $19,000, $19,000, $20,000, $20,000, $45,000), you discover that it is $19,000. That is more in line with what the majority of earthworm farmers in our example earn than the average or mean of $20,889.
