Does he see a performance variation by the mean?
Does he see a performance variation by the standard deviation? If he does, is it a performance improvement or a performance deterioration from the last year? Why?
Now, imagine that you are a citizen receiving fire protection services from this local fire department. How do you evaluate the response times of this fire department, by the mean, by the standard deviation, or by both?
If the average response time improves (shortens) but the standard deviation of the response times deteriorates (increases), what is your conclusion of the performance as a service recipient? In other words, do you want a quicker average response at the expense of a more unpredictable response? What is your recommendation to the director on which statistical measures he should use and how he should use them?
