DO YOU WANT TO BE A FOOTBALL OR BASEBALL COACH?
In statistics, standard deviation is a very useful tool. How many agents have ever explained your value proposition to the buying public with standard deviation?
In practically every aspect of modern life, we are overwhelmed with statistical data. Don't believe me? Watch the evening news and count how many statistics are given.
Baseball is strictly done with stats. In fact, every single pitch and its result is counted and measured. This why baseball managers are so calm and football managers are so hot headed.
Every baseball play has been performed thousands of times and the players know from statistics exactly how to execute no matter where the ball is hit. Football is completely random and it leads to coaches tearing their skin off over their heads. Last time we ran this play we gained 10 yards, this time we lost 10!!
So, if you are selling, do you want to be a baseball or football coach?
Why is standard deviation important?
