Why would one want to use a trimmed mean instead of a mean? In your answer please provide a numerical example that demonstrates the advantage.
What will be an ideal response?
Example and answer will vary. The heart of the answer is that because the mean is susceptible or sensitive to a few very large or small values—in statistical argot, it is “not resistant to outliers”—analysts sometimes modify its calculation by dropping or excluding some percentage of the largest and smallest values. The result is called the trimmed mean. This tactic automatically removes the influence of the discrepant values. The example should demonstrate this.
