I work as an Enterprise Datawarehouse designer and I work with numerous Data Analysts.
I am a Data Warehouse professional and my role is to equip business decision makers with numbers so they can make better strategic decisions and make a apple-to-apple comparison.
Is this supposed to impress people and make your position more valid? I've worked with some data warehouse programmers and managers in my time and my experience is that their heads are so deep in the code and business processes they are consistently unable to look at the big picture.
And to your comment about working with analysts, I work with a former NFL player... it hasn't improved my throwing ability or 40 yard dash time yet.
But, since you seem too engrossed in statistics to consider another logical response, I'll give you a simple example.
Town A has 100,000 people and needs a new plow truck at a cost of $60K.
Town B has 1,000 people and also needs a new plow truck at a cost of $60K.
Let's assume all people earn similar incomes and are taxed equally at $1,000 a year (even though we know that's not the case in rural towns).
Town A brings in $100,000,000 and received a benefit equivalent of .06%. Town B brings in $1,000,000 and received a benefit of 6%. They still paid for their equipment, yet because of minimum fixed costs, Town B is unable to dilute the cost per person as much as Town A. OMG freeloaders!
If you are helping people make business decisions and don't understand that variables like this can easily skew stats, then I feel for your clients.
